Ahhh alas you are correct in an mma fight you do have to worry about alot more then just being choked or submitted. Strikers learn grappling to be more well rounded, but come crunch time, they resort to what they know best,hitting. The same can be said about grapplers,they learn to strike but come crunch time they resort to chokes/submissions. Both fighters have decent amount of knowledge/track records in mma, but keeping with in the theme and looking at the facts, Bj is going to strike gsp and force gsp to shoot and take it to the ground,this is where the level of the ground game becomes a factor. Bj is known to work for positioning,what makes you think him being hit or him doing the hitting is going to make any difference.If the game goes to the ground Gsp will lose. I gave it to Bj because he can take a hit as demonstrated in fights of last. I dont think I ever really saw Gsp get hit real hard? If he hasnt he just might this upcoming fight. The only way I see Gsp winning is by a good solid shot to the jaw,and I mean solid. Maybe a knee to the face if Bj shoots for the takedown. But again Bj isnt stupid and would probably pull a grecko roman style takedown from up top. The one thing Gsp does have going for him is dynamic explosivness. If he could work the ring and jab away at bj ,only to suddenly explode on him throwing every strike he's got and smother bj, then he could creat small windows of opportunaty,which could result in the solid shot I was talking about.
