It's called "hype" for a reason. Every year, someone who's pegged in January to be a "can't miss" top ten pick falls to the brink of round one (or all the way out of it) come April...or "May" as in the present case. This year will be no exception. The trick is guessing who will fall and who will climb (because someone has to fill the slots).
From all I've been reading re which teams are smitten by whom, I think the following players will fall to #15 while these others will take their place and therefore be gone when the Steelers pick:
Fallers: ILB Barr, WR Watkins, TE Ebron, OT Lewan
Risers: WR Beckham, WR Cooks, QB Manziel, CB Dennard,
I'd go so far as to predict that the Steelers will pass on both Ebron and Lewan, but they'll take either Barr or Watkins if they're available...but they'll pass on Watkins if O. Beckham is still on the board, which he won't be.
Other risers: CB Fuller, LB Shazier, TE Amaro, LB Van Noy, DE Tuitt, S Buchannon, LB Mosley
Other fallers: WR Lee, DT Ealy, DT Jernigan, TE Niklas, DT Hageman
What about you? Who are your risers and fallers?
