I don't even think he's necessarily good (at least right now) I just think that the rush to DFA the guy is extremely premature.
I think he still has the talent to be an ace, but I'm not sure he ever gets there because of the control.
You want my honest opinion about Rodon, and not my troll opinion?
Rodon probably is never going to be an ace, because of control problems. He still has great stuff, even throwing 92-93 and he can definitely top out as a #2-3. I believe the same about Giolito. His control issues will probably prevent him from being an ace, and at worst both will be #4-5 starters that frustrate the fuck out of their fanbase.
