The concerns are valid, but there are plenty of larger concerns on this roster. I think people unfairly pick on Happ because we have other comparable options, but that depth is going to play a huge role this season. We need guys like Happ, the bigger problem is that we are relying on a guy like Morrow to be one of the leaders of this rotation and that is a huge gamble. Plus we have no legitimate #4 SP right now that we can count on to eat innings. Santana could change things a bit, but who knows what happens there. My bet is he ends up on another team anyways.
