I think he WILL be the one to beat BJ, even though BJ is definitely my top favorite fighter Tyson is in a close second. Tysons style is balls to the wall for 3 rounds or until you get knocked out, or submitted. BJ can't handle that, its not his style. Now BJ I think can out strike him, but Tyson has alot of pure strength and incredible heart if he can keep pressing BJs cardio will be done with quickly (BJ has new-found dedication, but he isn't a wrestler and even Tyson Griffin has god-like endurance for a wrestler). But this is of course if BJ doesn't knock him out/tko him, and if Griffin can avoid submissions (which he does pretty well).
