Brett Favre believes Aaron Rodgers will be back on the field next year ... and when he ultimately straps on his helmet and shoulder pads again -- the Packers legend tells TMZ Sports the QB will be "as good, if not better, than ever."
Of course, Favre says there's at least some chance Rodgers calls it a career after he snapped his Achilles during his Jets debut on Monday night ... but as a guy who's spent years around the signal-caller, Favre just doesn't see a way this is the end for Rodgers.
