So i read thru most of the comments....i don't agree with the "Missing Randal Gay" aspect because MJ plays nickel in those situations with Sharper moving to FS on passing downs and MJ is very very good@the slot.
Ever notice how Sean Payton....when game planning says "we have to be selective in the throws we make@certain corners" Usually when we are facing an elite or very good CB. Greer is suspect on balls thrown over his head that he can't locate. Period.
He just doesn't have great ball skills...which is what separates him from say a Revis. What he does have is extremely good footwork. comeback routes...slants...curls...he normally plays those balls pretty well..but if u put one over his head..while hes in tight coverage.....u have a pretty good shot@breaking the Greer Code.
