BJ had a few surprise takedowns that surprised Fitch. He then went for his (predictable) RNC. Once Fitch got in stride, he pounded BJ into another world. The fight wouldn't have lasted another 30 seconds. You could see BJ's will cracked like a dry stick.
1. I feel for Fitch - he went for it, just too late in the fight.
2. Where is BJ's world-class BJJ??? He only goes for the RNC - only works with a damaged opponent.
3. I hope they rematch soon, but I suspect BJ will find another option.
