Warren Moon says Aaron Rodgers deserves a lot of credit for shutting down his comeback efforts this week ... explaining to TMZ Sports things could have turned dire for the QB if he had continued his push to get back on the field.
The Hall of Fame quarterback -- who knows a thing or two about playing into his 40s -- said on Wednesday he's glad Rodgers has decided to stop his pursuit of rejoining the Jets this season because he had a real fear the 4-time MVP could reinjure himself.
