Cutler has always had a discrepancy in his symmetricalness. If you look back over posts involving the Jay/Ronnie debate, this is the major debating point Chad uses against Jay. His right leg is smaller, and he hides it by using it as his plant leg during many poses.
I think it was MadMax who said, paraphrasing, that Jay had nerve issues similar to Ronnie, and like Ronnie's left lat/tricep, Jay's right side was being affected. I think there was a tendinitis issue as well hindering his arm training.
The above photo is reversed....his right biceps is the one with that distinctive peak. Just an observation.
