On Re-framing Dangerous Play

I’ve talked before about the differences between WFDF and USAU rules on dangerous play. But there are more fundamental problems common to both rulesets, and in my opinion we need to look at the whole question of dangerous play in a new way. If we’re serious about reducing it, then we need a closer analysis of what it is and why the current rule doesn’t always prevent it.


Currently, dangerous play is a foul by the person who could see it coming but does not pull out of it. It makes no difference who would have got the disc first  only who had the opportunity to see the collision coming. Continue reading

The Logic of Playing 4 Women

There’s a default in most high-level mixed teams to play 4 men most of the time. The data in this useful article show that quite clearly.

But continuing that default behaviour under the new rules would be foolish. It is logically impossible that both teams are correct to call 4 men most of the time, if their intention is to win the game. Continue reading

On Referees, TRGs, and WUCCs

You’re probably thinking by now that I’ve said all I can possibly say about the nuances of the various officiating systems. I do tend to go on about it a bit¹.

But here we go again…

Is there any meaningful difference between a referee handing out punishments during a game, and a group of officials meeting afterwards to discuss retroactive sanctions? Continue reading

Pulling, Part 4 – Rollers

(See Parts 1, 2 & 3 on these links)

The roller pull is my absolute favourite throw. You don’t always have the right wind for it – a left-to-right cross-headwind is perfect (for a right handed backhand thrower) – but when you do it’s enormous fun to use, and there’s no better feeling in ultimate than watching someone lay out to stop the roll just as the disc says, ‘Not today!’ and turns sharply towards the sideline out of their despairing reach.

Why rollers?

Check out these two pulls (on consecutive points, so presumably in similar wind) from the recent Pro women’s game.

Pulling, Part 3 – Blades

In my first recent post on pulling, I talked about distance versus hangtime; in the second (published on Ultiworld) I discussed the shape of throws that might help maximise these things.

But today, something completely different. There are times when a traditional pull is not the best option. In fact, I’d say that you should be looking at rollers and blades far more than most teams currently do. Continue reading

On Cocking the Wrist


Should you cock your wrist to throw a backhand?

That question, like so many others, is a lot more complicated than it might seem. If your coach is saying you must cock your wrist at the start of all your throws, they’re wrong. But if they’re saying you should never do it, they’re wrong there too.

Let’s look at some examples of throwers and their wrists, many of them taken from Joe Marmerstein’s helpful archive of throwing form. Continue reading
