I thought performance-wise they were about even, with maybe a slight nod to AJ. But upside is definitely Sims, personally I thought he looked like a potential future NFL QB out there, how long has it been since we've had one of those. He feels the pressure and steps up in the pocket, he looks receivers off, anticipates cuts and receivers getting open, has a quick head, seems very decisive, has a quick release, doesn't panic, he's calm after he or his receivers make a bad play (unlike AJ, who gets noticeably frustrated), he claps after bad plays like CNS, and he takes criticism well (I've never seen him angrily walking away from CNS when CNS is trying to tell him something). Sims made some bad plays in the first half but he never got frustrated, in fact I remember him clapping as he came off the field. He's much more mature and much more of a leader than AJ IMO. And I think the team will ultimately respect him more.
