Interesting questions despite some of the posters trying to turn this into a boxing vs MMA thread as usual. I happen to disagree with you though. I think there could be some mid level promotions that attempt to have cards that have boxing and MMA matches but I don't see it catching on with fight fans. To me the sports are different enough that they will stay separate at the highest levels As far as a Bo Jackson type appearing? Why not? I could easily see in some years time, one guy holding a major belt in both boxing and MMA. The pro boxer with fairly well developed ground skills could arguably be the guy to do it. We'll see.
