Good thoughts Mr. King and thanks for the video. I did see the delay..part of that was due to the coach giving a hand signal and talking to the R2. I had another thought on a scenario, what if number 20 is the second sub waiting and as the first sub is entering, number 18 from the bench swaps with 20 with no perceived delay?

If you or your partner believes no delay occurred, then you don't have to issue one. It'd probably be a smart move to caution the coach for next time, but otherwise, I'd say to allow it.

That's the beauty with Team Delays: most of the time, they're at your discretion. You issue them whenever you feel the match was delayed by an unnecessary action.

For example, when I have captains who enjoy continuously approaching the stand to question a judgement call, or if I have to stop a team's behavior (continuously yelling "TOUCH!" for ex.), I issue team delay warnings.

So it's totally at your discretion, but in the situation above, I would let it fly with a caution to the coach.
