Yes, I think he should retire right now - while he’s on a high note!
timing is everything
Yes, I agree. Denver will want to sign Osweiler, but I doubt they would want to pay starter money for two QBs. Manning has lost some of his zip on the ball, and that system is really not the system he has become accustomed to. I don’t see any upside to him returning, and lots of risk. Hope he rides off into the sunset...
