People discount Thompson because of his style. A style that waits to clip you with a shot- as slow as they come, and when he gets you in danger and dazed, just pours it on you non stop.

Funny thing is if you can stay away from being clipped AND you can move around the ring if you do get clipped, you can win UD's against him. And, if you have power, do what Wlad did and that's stop him late.
