I've been thinking Coby Fleener could be the surprise pick.
Another could be Rueben Randle. He's a big athletic WR that could help us in the RedZone. Quality kid from a big time program and happens to be a junior which Tomlin seems to like.
Don't think it would happen, but Josh Robinson of Central Florida could be another surprise 1st rounder. Seems like one of the best athletes at the CB position in the draft. He's a junior too. Not a big program. And he's a little short at 5'10" but is around 200lbs and seems like a guy that Lake/Lebeau could really work with to turn into a prototype Steelers corner. Seems a little reachy and not a sure thing. But has a lot of upside.
