I think Brees arm isn't fine

Other than that I agree with your post. But unfortunately for the guys who start out with marginal arm strength that can be something that age hurts them and hastens the end.

Ryan is sort of in that boat. Manning was for sure too. But with Ryan it's going to be interesting to see whether he can build that arm up and do better at muscling those deep outs.

Brees I think is done. His ball floats way too much.
