I normally wouldn't do this, but there is a poster on one of the forums I lurk that breaks down prospects very well. Here's what he said about Mike Evans that worries me:
In my book, Evans' ceiling is Jimmy Graham. In fact, the more I look at these wr's, the more I think the Steelers shouldn't take one in the first round. Just not a lot of separation between the 2nd best and the 10th. There's a ton of talent at receiver this year, probably 20 guys with good skills and/or physicality. The exception is Sammy Watkins. Guy is a stud who can do it all. Haley would lose his mind him. He's basically Antonio Brown, but bigger, faster, stronger and more athletic. Not as shifty, though.
