I usually pick which defender I manually control by assessing the play, then figuring out which position is most likely to fuck up and then taking that over. This year when I look at the field presnap it always feels like there are at least 2-3 spots that I feel like are probably going to fuck up their assignments badly.
Yeah, I don't even know whose mistakes to try and cover up. It's like trying to plug holes on a sponge, but you only get one peg!
