Mayweather is the only one I would feel confident beating Simms, and thats because of his speed and he does what Simms does better. I like Simms against ODLH, SPinks would be close, POwell, haven't seen Dzinziruk.

Simms is a really good technical fighter with a good physical arsenal to boot. He reminds a lot of TOney who wasn't just technically proficient, but also a good athlete.
