Tyson, but unfortunately if he replaced Kellerman, it would be on Larry's days off so they wouldn't be side-by-side. It wouldn't happen anyway though.
C'mon guys, Tyson doesn't have the voice for commentary. He has good boxing knowledge, but I don't think he has the ability to articulate it.
id like to see iron mike just to have a former boxer giving his anaylisis plus he is a boxing historian so he knows his stuff
