He should have learned for form Britney. Both party in Vegas the week before, they both perform like shit.
He should have learned from the Rampage fight as well.
Three things Chuck has to do.
1. Stop acting like a rockstar. His lifestyle is catching up with him.
2. Increase his skillset, and change his fighting. He keeps his hands WAY to low. He isn't going to be fighting shoot first grapplers anytime soon, he needs to keep his hands up. He needs to be lighter on his feet, and cut angles.
3. Quit trying to get the highlight reel KO, change tactics.
If he would have gone back to his wrestling and taken Jardine down, he could have set up his overhand right with a level change, lunging overhand. He isn't a threat to take anyone down, because everyone knows he won't shoot.
