He certainly didn't put the Pats in the hole (that would be the LB corps, letting JAX run and slot all over them), but whoever decided Corderelle Patterson would be an effective gimmick WR (end-arounds, bubble screens, jet sweeps) is being proven wrong week in and out. He was put in two key high leverage situation (3rd down, deep in JAX territory, key scoring drives), and blew it both times:
* 3rd & 10 at JAX 11 - (2:56 - 2nd) (Shotgun) T.Brady pass incomplete short left to C.Patterson.
* 3rd & 4 at JAX 26 - (14:54 - 4th) (Shotgun) T.Brady pass short left to C.Patterson to JAX 28 for -2 yards (D.Hayden).
He stumbles in open space and generally looks out of sorts - like a WR trying to play RB, which he is. I don't blame him at all, really. He's built like a possession receiver, but doesn't have great hands. He's concentrating to look the ball in, but seems to forget how to advance, and it all goes to hell.
The hubris of the Pats to think they could "coach em up" into something he's not (Tyreek Hill, I guess) isn't Belichick's biggest GM mistake, but it's just a waste of time.
