The veterans, sans Bundy, have done a good job showing the younger guys what not to do like get hurt (Gray), sign late (Archer), blow leads (Duffey) and just get destroyed and give your team no chance to win (Thielbar).
I state "sans Bundy", because he did have that one game where he gave up four runs in the first inning, but then he proceeded to only give up a couple runs over the next five innings. It was still a loss, but he chewed up six innings and the bullpen didn't get wasted in the first game of that series.
Wes Anderson can tell you how fantastic Mr. Fox is, but I doubt he'll be able to coach up any of the Twins young pitchers.
