I can count no less than 10 guys in this system and probably every other who have the POTENTIAL to be legit aces. But as you look around MLB....there's a reason why there are so few aces. Mark Rogers can be an ace. I can't fathom anyone arguing that based on his pure ability. But, he's missed two full season, has control problems, still has some, some mechanical issues repeating his delivery, his secondary pitchers aren't where they need to be and he's pitched very little relatively speaking to a budding 1/2 type pitcher. He could be a super 4/5 who has some great games and then goes 3 2/3 with 6 BB's 3 K's and gives up 5 runs, and he could do both fairly often as it stands now. Jeffress, Odorizzi, Heckahtorn, Peralta, Scarpetta, Arnett(even with his struggles), Hell Parra....and others. We've got lots of "potential aces". I don't have much faith in any of them save for Odorizzi and he'd have to become a pitcher like Gallardo, a questionable ace in somes minds to make it to that status. So I don't think we're down on him, we just see what he's done and don't see a future ace. That could EASILY change. Hope it does.
