When I'm playing, I'm on the field. I know which way an opponent's forehand is, even if he's lefty. I do not know on which side of the field my bag is sitting on. And we are supposed to have people on both sidelines anyway, so both sides are home.
While I'm here, I can't stand that back of the endzone cut. Especially the endzone drill that promotes it.
Hate it when the team wants people there 60 or 75 or 90 minutes before the game and at least 30 of those minutes are spent chit-chatting or lazy stretching or standing and throwing unrealistic passes. You can do a full warmup (including adequate throwing) in about 30 minutes if you are efficient. If you have some specific team thing or a special throw you want to add in, too, add 10 minutes. What's the big deal about getting there 20-45 minutes extra early? It's time wasted, energy wasted, and focus wasted. Those things ain't free.
My kid's soccer team had a drill using one ball where each kid was standing around 95% of the time before having about 5 seconds of "skill work". Hated it enough that I got up and left to go work out.
And now for things I like.
