I know how to get the corner to come down close to receiver, but I mean when I player lock him like it's rtg and am in man coverage and the wr comes off the ball I thought there was a button to jam him

on xbox its rb i don't know what it is on ps3 probably one of top trigger buttons when you press it you can direct which way they go after a successful jam either left or right.
If i'm close to the side line i try to force them out.
Also if you jam complete them before they can even get started sometimes they won't even finish their route.
