IF this really happens, and is not a work, I think it will settle the Tyson vs. MMA question once and for all...
1) If Fujita G&P's his way to an easy victory (or better yet, taps Tyson out), as most of us expect, it will show that MMA is the "ultimate" combat-sport.
2) If Tyson or Fujita wins a difficult and bloody decision it will show that the two sports are roughly equal.
3) If Tyson KO's Fujita easily, it will prove that boxers are light-years ahead of MMA'ers in terms of durability and striking power. So Pit Dog, Judo Guy and others will be able to crow.
Should be good, no matter what.
It'll never happen.
