Teddy's in a great place for him - somewhere with a high-quality defense, some other offensive talent to do the heavy lifting, and that has been starved of even reasonable QB play for so long that his low-risk, high-percentage style looks amazing. It helps a lot that they've played the Division 2 of the NFL so far but with that defense Denver might sneak into the playoffs as a Wild Card (assuming the Chiefs wake the hell up) and bow out in the first or second round a la Alex Smith as the peak.
For Denver fans, that will be amazing this year. No question though that Carolina is better off and I still speculate that Teddy drank his own Kool Aid and needed a dose of humility that he likely got after last season. He never should have been brought to Carolina in the first place but what's done is done and everyone is better off with him elsewhere.
Sam is looking cautiously promising with plenty still to prove. it's encouraging that he seems to have already made some strides vs last year in NY.
