I can see not liking it if you think there's a chance he's going to get a 25-man spot over someone better, but the list of things that have to happen for Wolf to get a rotation spot is long enough that this isn't a concern at all.
FWIW, I'm not saying that you made a bad deal. I just think the Gibson + 6th OV + Draisaitl for a 27-year old 35-goal guy is fair. The deal looks much, much better than it could have with more lottery luck.
