I watched several full game videos of many of the top edge rushers in January. He was easily the worst of the guys targeted for a top 50 or so pick at the time. I recall D Barnett looking strong and accomplished and he was going at the same time -- and it was night and day. Wanted him bad for Pittsburgh, but his stock has since risen. Same with Soloman Thomas. Back then these guys were pick 'ems in the middle of the 1st. Much rather have Reddick or Watt at this point.
When I watch players, at any position, I try to find reasons to have an opinion. Good or bad. It serves me well in my leagues (which most include IDP) and with him he was definitely a "bad" listyed player when compared to his contemporaries.
