The similarities to Jay Cutler are striking. Kucklo actually has better proportions, better bellies, etc IMO, but the quality to the muscle is similar. Though Cutler didn't turn pro having done as much GH and insulin already, I'm sure (I bet Dante would swear Kucklo hasn't done any insulin yet, very little GH, because he has such wonderful genetics).
The frame and proportions are very pleasing but added size, which he will no doubt try to pack on, will only come with even more peptides so the very crisp look will never manifest.
Can he become Mr O? If he can stay healthy and stay motivated year round a la Cutler, why not. It's not completely impossible.
