He has a ton of items to work on this year and while you can consider them small he needs to loosen up on the mound and is way to stiff. It does not seem effortless coming from his hand because his lower and upper body movements are not in sync. I agree that he could use better footwork, but he needs to maintain a consistant in everything he does, especially in the wind up. I would like to see a bit more drive from the lower body. I would really like to see a greater emphasis on the follow through, as he pulls up early on occassion. These are things that will improve his command and lessen the impact on an already repaired elbow and shoulder.
I think he is better out of the stretch right now, so I know he is more than athletic enough to make the adjustments.
In my mind, he is better off serving as a relief pitcher until he can effectively correct these items. They may stretch him out in the minors, but he is going to be middle relief or loogy
at the major league level. It is still not bad, but until he can repeat his delivery and clear up the minor flaws it is safe to limit his innings and pitches to keep him arm healthy. He ceiling is back of the rotation, but he has a few things to correct before you realisically will see him in that role long term.
