As time goes by and the more time he misses, we can forget just how good our QB can be when healthy. If he really is better than he's ever been, I'm definitely excited to see what he can do. Even if he's just "only" as good as he was before surgery I'm still pretty intrigued. Here's a nice reminder.
I'm glad they are doing their due diligence with him. I watched him a bit last season and I thought he was worth about a 5th-6th round pick without knowing he had issues with coachability(I heard about those from Matt Miller on his Stick to Football podcast when he declared for the supplemental draft). Now I'm wary giving up even a 5th... but that's why Ballard and his staff are paid millions - to do their research and see if there is fire where the smoke is.
Scheme fit was definitely a big thing in the draft this year. Ballard even sacrificed value to get guys that would fit the new 4-3, which was a good change of pace from the Grigson days (Bjoern Werner comes to mind). If he fits, I'm all for it, if not, pick up some players who get dropped during cuts and see if they fit our scheme better than someone else's.
