Checked a few sites this morning. Both Walter Football and Kiper had the Steelers as day 1 winners (Kiper also had Bengals as a winner). Here is what Kiper said:
I always worry when the pundits declare you an immediate post-draft winner because they are wrong so often...Pittsburgh Steelers
The pick: Jarvis Jones, No. 17
Summary: The Steelers saw the board set up really well. I thought they might be split between Jones and Tyler Eifert, but they really need another pass-rusher, and when the guy who led the country in sacks and tackles for loss -- and he did it against plenty of SEC competition -- is sitting there at No. 17, you take him. Jones was No. 1 on my Big Board for much of the year, but dipped some during the evaluation process after not working out in Indy and then not running well at his pro day. Well, turns out he's better wearing football pads than Under Armour. Love the value here.
