I honestly think Bisping is planning to win by decision or by late finish in the fourth/fifth round. He doesnt wanna get embarrased by getting KO'd twice by an inferior version of the fighter he fought the first time. Bisping has a huge lead in the cardio, striking and defence department but Hendo has that 1 punch KO power. Bisping has put himself in a a "must win" situation by fighting Hendo. Hendo has a chance but only for the first three rounds, I think.
I think there is so much value in Bisping -200 and Bisping dec lines. Bisping knows how to win points and honestly, he has improved so much over these past couple of fights. Hendo has the H-bomb, so fight ending ITD is a possible hedge.
