It's a real shame, because he has all the talent to be a top 5 receiver. He has the speed, the frame, and yes, the hands. Not being on the inside, I don't really have a read on what the problem is.
If you watch the game and focus on him, it looks like he takes some plays off. He loses concentration. He just doesn't do the little things that make good players great.
He's basically a tease. He's inconsistent right now, and his mistakes are costing us drives (and today, a game).
Having said all those things... he's hardly a scrub. That's a bit harsh.
