Why do people seem to view Bradley as some weakling?

[Ron Swanson]

If he stops getting put on queer street by gatekeeper level talents then he'll get his rep back. But he's been seriously hurt many times, there is a decent chance his best days are gone.

Bradley is a top fighter. He is very well conditioned and can fight at a very high pace. For all his muscle and physique he can not punch as hard but his boxing skills are up there worth the very best. Bradley does fight to the level of his opponent but Tim would give Floyd, Thurman, Khan and Brook all good fights. Bradley should not be viewed as a weakling.
