Figured this would be a good place for this.
Remember Avery's catch where he kinda stumbled and went down? Look at this picture:
Avery's hands have betrayed him so many times that he refused to reach for the ball there. He's no longer willing to hand-catch a pass because he doesn't trust himself to actually secure it. Instead he turned, took a bad step and cradled it into his mid-section. In so doing, he just fell the hell down and cost us a HUGE YAC play.
This is a display in how a QB can set up a WR extremely well for YAC yards and how a WR can give/take those yards. Smith put that ball in a perfect spot for Avery to reach out and grab it in stride, make a cut upfield (which was clearly the design given the downfield blocker) and perhaps take that thing all the way across the field for a score as Avery has outstanding jets.
Sometimes blaming the WRs or the O-Line really is appropriate.
