colby talked a big game long before on how he was the best and going to prove that by winning the ww belt and he failed to do so.
he's dreaming if he thinks that his stand up was better that night, if your wrestling was better than why not use it instead of standing knowing your jaw is broken simply just shows colby has no fight IQ or oblivious that he was losing in the stand up and could've used td's to secure points if he thinks he could outwrestle usman.
as for being tough, sure I'll give him a pat on the back for continuing on...however it's nothing to brag or make a big stink about. many fighters have continued to fight with injuries equal to or worse such as broken nose, broken orbital bone, hematoma's, ect.
