Two things:
1) Is the Punt Returner's logic the same as the Kick Returner's logic? It seems punt returners will run to the outside, but kick returners just run straight up the gut every time. Maybe the kick returner logic should be the same as the punt returner logic.
2) The wedge seems to move too far back before turning around to block. So, the kick returner just runs by the wedge instead of the wedge opening a lane for him to run through, he just runs past them. Maybe the should form up sooner to be able to start blocking before the kick returner gets to them...
