Look at that 1st screenshot again. The CB may be behind him but he’s already squatting while Marvin is in full go mode.
Every legit NFL Wr is open at that point and going to beat that CB.
again you think he's squatting because it's a freeze frame of a play where you know what the end result was. If we had the full tape of the game we could find dozens of examples where if I freeze the shot, the CB is "squatting" and yet the WR doesn't end up open, let alone 20 yards open.
If he stays right just a beat longer yes he's going to see that MHJ is now breaking free but at the point he got off right and went left, that wasn't the case.
I think Marvin is going to be an absolute star, next in the line of great Cards WR's, Mel Gray, Roy Green, Rob Moore, Anquan, Fitz, D Hop, I think he'll eventually be in that group, probably a notch below Fitz but who knows he's faster than Fitz ever was. I hope we get to the point quickly where Kyler trusts him the way he did D Hop.
