The Steelers get a talented big target at WR with Clemson's Martavis Bryant.
This is a tall 6'4" receiver with some speed (4.4ish 40) who has all upside as far as I can tell, with the right mentor. Mike Mayock mentioned some immaturity issues as a potential problem, but I expect the Steelers coaches to get that under control right away.
He's potentially a big playmaker for the Steelers. I don't expect him to have an immediate impact - from what I can remember from watching Clemson play this year, he can stand to tighten up his route running, but I think the raw talent he has makes this a great pick for the Steelers. With some work, he could really be a great target for Ben.
I like this pick a lot.
