Nix taking Graham over Wilspn is the most obvious mistake, but how is that on Whaley? What is on Whaley is the complete mishandling of Manuel. Maybe Kolb was the best option, I don't think Fitz wanted to stay. However, and I've said this before, rookie HC, rookie OC, no QB coach, it's just idiotic. By Hackett's own admission it was a blunder.
Tha being said the Sheppard for Hughs trade maybe one of the best trades of this young century. The trade that brought both EJ and Kiko, even if EJ is a bust, which I don't believe, is a pretty good move. Sammy trade? Looks like we gave up a mid first rounder for him, not bad.
In the end I think Whaley has done more good than bad.
