Oh brother We're talking about MMA not BJJ. Has BJ EVER submitted anyone in an MMA match from his back? Here's a hint...NO! To say that BJ would have been able to submit GSP from his guard, has GSP not has some leftover lube, is absurd. He hasn't done it to anyone else, he's certainly not going to be able to pull it off against GSP...
Did you say submission in mma, or did you ask if BJ ever made a submission from his back, you human shitstain? Learn to read your own fucking words.
By the way, how many people has BJ submitted off his back?
Further
more, if you knew shit about bjj, when you are in your guard, you usually don't plan to maintain that position but look for an opportunity for reversal to gain a submission.
I am glad you enjoy rooting for cheaters. When GSP and his glass jaw gets KNOCKED THE FUCK OUT, I hope you won't be on hear crying that he "didn't have enough time to train," or that it "was a lucky punch," or that "the other guy had hidden brass knuckles, " or some such other bullshit.
When has GSP announced he is moving up in weight class to test himself with a greater challenge?
