Let’s take a look at the other side of the spectrum- Zone defence. In zones, defenders take up a position relative to the disc and then cover that space. Zones tend to have one of two goals. Either zones pressure shorter options and bait throwers into attempting high risk throws, or, zones leave easier options in the backfield open, and contain downfield options in the hope that over many throws the offence will make an unforced error. Zones thrive in poor weather conditions where the likelihood of routine mistakes and difficulty of expansive throws both dramatically increase.

The key problem that zones face is that it’s almost impossible to take away all the options when players take up positions instead of marking players. Therefore zones tend to rely on the offence’s poor decision making or execution errors to generate turns. Zones also require communication and awareness from defenders – keeping track of the disc position, restricting the space on the field in coordination with your teammates and avoiding double coverage – all complex processes which leave plenty of opportunity for critical errors, even in the very best zones.

Few teams play zone defence as a primary strategy in modern day ultimate. Throwers are so proficient at making precise and patient throws that zones may slow the tempo an offence but rarely cause consistent turns. Of course zone defence in adverse weather situations remains prevalent but transition zones are becoming more and more popular. Teams like Raleigh Ring of Fire and recently New York Pony may play zone for the first few passes or until the disc passes a certain point on the field before snapping to 1-1 matchups.

Japan v USA p07: Japan Pointing & Shouting but leaving Schlachet Unmarked

Japan don’t care about marking players who are behind the disc – you can see #17 look around to find alternate marking options when his player occupies the backfield. He does however make a mistake at the end of the clip by paying too much attention to the thrower and biting on a backfield threat.
#3 Yasuo Takahashi, top left, bumps into Beau early on in the clip, then points and shouts in order to pass him off to a deeper defender. When #19 Mickle comes near to him, he takes him as a mark, but doesn’t follow him into the backfield – instead takes the force.

#19 Masashi Koike as the central defender is the first to point and shout to pass off an offence player who is jogging deep. Note how often he looks at the disc, checks the space around him, points to any nearby offensive options, and closes down offensive players when they are potential threats (depending on the status of the disc).

#7 Yuta Inomata enters screen left after a few seconds, and is also clearly conditioned to point and shout at any nearby offensive players, as he does three times in these first few seconds of defense. He makes a mistake however – not marking #4 Schlacket, who receives the “zone-busting” pass at the end of the clip (though I would not call this defence a ‘zone’).

The reason Inomata did not mark Schlacket was two-fold – firstly, he was in a zonal mindset, (falsely) trusting that #19 Koike would pick up any player in the middle of the field.
Secondly, he was drawn towards drawn towards a deeper offensive player who must have posed a threat (we can’t say for certain as we can’t see the deep marking). #19 Koike, who starts as a central defender, was occupied with a live offensive threat on the sideline, however by slightly poaching he sent a false-positive signal to #7 Inomata that he could cover a central offensive threat, hence why this player was left unmarked.

If the deep marking was tighter then this would have sent Koike a positive signal that he could commit to marking Schlacket and not worry about the deeper threat. Of course the tighter deep marking would have increased the risk of a USA huck – which was likely against the general Japanese team-strategy for this game.

The interesting positive theme of this clip is the repeated pointing and shouting whenever a Japanese defender identifies a potential offensive threat – even if it isn’t always directed towards a specific teammate. This is clearly a cornerstone of the defence – communicate the location of offensive players through gesticulation and vocalisation.

What could be improved, is making sure every offensive player is covered, as this would help prevent the “zone-buster” to Schlacket. It’s worth noting the root cause of the offensive player being unmarked was a knock-on effect of poaching (by #19 and the deep defenders), meaning #7 Inomata felt he could pass off Schlacket rather than mark him.

Spectrum of Defence: Sustained Poaching (Part 4)
Spectrum of Defence: Flexagon Defence (Part 5)

Hi everybody, this is the spectrum of defensive coverage, which categorises the degree to which a team is defending space, or defending players. In this video we’re going to look at examples of the different concepts along this spectrum, their pros and cons, and why defences might want to play them at different times. For more info on Flexagon defence, which is my speciality, check out the videos on the felixultimate YouTube and patreon channels.

On the far left of this spectrum is Match defence where each defender matches up against an offensive player and aims to stop that individual getting free. Conventional match defence is extremely individualistic allowing defenders to pick favourable match-ups that correspond to their abilities. The basic teamwork that is happening at this end of the spectrum revolves around the force – the defender marking the thrower is tasked with pressuring particular types of throws or throws to a designated area called the break side, whilst the downfield defenders mark their matchups accordingly, usually by guarding moves to the open side as a priority over moves to the break side.

Offences exploit the reactive nature of match defence by forming vertical and side stacks which lead all the defenders into a small area and leave large open spaces for the offence to cut into. Match defence is also vulnerable as it places a disproportionate responsibility on the person marking the thrower to pressure all break-side throws.Most ultimate players have probably run a 3 person break force drill and have routinely broken the force time and time again, try this drill with your eyes closed on disc and you may be surprised at how successful you can be. [Insert video of blindfold breakforce, record one at next disc golf sesh] This means that break side throws are common in almost all high and intermediate level ultimate games.

Few high level teams play pure 1 to 1 match defence nowadays, most encourage a level of flash poaching and reactive switching in situations where a score must be stopped, or where a turnover can be generated. The more that players can lock on to a 1 to 1 match-up, the less on-field teamwork is used, which simplifies the task for defenders and allows them to focus on shutting down their matchup. This leads to a sustained level of pressure over time, with many bids possible from an athletic team. Teams that tend to have an athletic advantage over their opponents like Clapham, Fury and Grut have used match defence to great success as they can consistently shut out their match-ups without the need for team Defence.

What is Flexagon Defence?

In this short video I introduce Flexagon Defence and break it down to show how Flexing defenders can use dynamic teamwork to cause trouble for predictable offences, plus a video example of Flex in action.

Flexagon defence is a hybrid defence – if you plot a spectrum from matchup-based 1-to-1 defence, to area-based zone defence, Flex lies somewhere in the middle. Sometimes it can resemble 1-to-1 coverage, and at other times it can resemble a zone, but it shouldn’t be described as being one or the other.
All the concepts on this Spectrum of Defensive Coverage are explained with examples in another video linked in the description below, be sure to check it out. This video focuses solely on Flexagon Defence.
Defenders in Flex switch marks as early and as often as they can, and they surround clusters of players including stacks. When the offensive players are spread out or isolated, defenders in flex mark 1-to-1. These coordinated team actions are executed mid-possession, triggered by particular offensive movements, and require strong awareness and communication skills from the flexing defenders. Defenders train to recognise when it’s appropriate to switch, to surround, or to mark 1-to-1, and they keep a constant on-field communication channel open so they can reposition, adjust, and adapt as a team accordingly.
The default force in Flex is towards the middle when the disc is near the middle, and toward the sideline when the disc is near the sideline.

This footage is taken from an indoor regional semi-final, though Flex is usually played outdoors. Reading form a tight stack in the centre of the space, the flexing Sussex defenders surround, and pick up players to mark 1-to-1 as they begin to cut. On the right hand side Zach picks his moment to switch off his mark and catch the interception.
The initial setup ensures little double-coverage as the defenders guard the open space. Despite an initial double-commit, there is quick communication and re-adjustment made before the offence are able to capitalise. Once all the offensive players are cutting, the defenders are marking 1-to-1 whilst looking to help each other. If the offence were to cluster together again, the defenders would return to surrounding them.
