I don't really know very many plays from the 4 WR set cause I run the ball a lot but a money play that I live to use is PA counter or something like that. You have a WR going deep, ur 2nd tight end going down the middle and you have your 1st tight end doing a blue route and blocking someone and then breaking away after a block. This is a play that is good for when you have like a 3rd and 5 because this play is very successful.
