Eh, Omari Ackmedov was a tough as matchup for Chris. Ackmedov has historically had really solid defensive grappling, and been hard to hold down. The fact that the Chris grinded that one out proved he isn't done.
Also, Covid and him moving his camp apparently stuffed up his training camp. Look, i'm not expecting Weidman to look anywhere close to prime, but I think he might look better than he did last time.
Plus, Hall is a low output striker, and has been susceptible to wrestling based gameplans in the past. I tend to think either Weidman via decision, or Hall via KO, while losing most of the fight prior to the KO. I doubt Hall wins a decision.
Weidman 30-27. Close fight though, wouldn't be surprised either way.
