I agree with what MizzouFan01 said below about Hawks...fringe AA. BUT...to your second point, I would have thought he would have developed much more by this time at Mizzou. I looked at the staff from their "title run" season in 14/15 and one of the main things that stuck out was that they don't have a strength and conditioning coach anymore (it was Larson at that time). They also had Clemsen and Johnston, who's coaching styles may have been different than the current crew. I thought Sammie Henson was on staff then too (that may have been the previous year when J'Den was a freshman). So I don't know...the injuries have seemed to pile up more and more and it makes you wonder if the training methods aren't working (or are overworking). It's either that or the worst luck I've ever seen (Surtin, Gioffre, Steed, O'Toole, Hawks, Rocky all had injury time). It seems to me that they need some new blood on the coaching staff. I'm guessing Maple is the heir apparent when Smith decides to retire, so don't think he's going anywhere. I love Dom and think he's great. Maybe the answer, as MizzouFan01 said, is bringing in a lightweight coach (Alan Waters, anyone?). And I think they need someone focused on strength, conditioning, and wellness.
Nitzel did have some bright spots this season and I was pleasantly surprised. He'll be a RS SR, so maybe they do RS Stillwell (although I'm sure he's raring to go after spending the last year at the OTC with J'Den).
I personally hope to not see Kade Moore in the lineup ever again. I'm being too harsh, but he is so frustrating to watch (almost as much as Gioffre and Conway) and I've given up at this point
