I think that Weidman as big to moderate underdog v Izzy is a must bet.
I don't know if I am crazy or what, but to me Weidman showed good improvement v Ronaldo. He cut the octagon well and used educated jab. This alone will pose more of a threat to Izzy than anybody that fought him so far in the UFC. And when we add the big frame of Weidman - he is a giant of a MW compared to the Stylebender. Also much superior wresting and grappling chops than anybody that Izzy had faced so far in his career.
We have to consider Adesanya is not a KO artist, not a heavy puncher I mean. Precise, but not a heavy handed one. So Weidman with his weakened chin I don't think we should be concerned with. I am not buyig the hype still. I am betting Weidman if he is the underdog for sure. Not a big bet, but I'll bet on him.
