Frank shouldn't have stood with Cung Le, but he did so to try to beat Cung at his own game. Admirable, commendable, but not too smart.
Shamrock took the fight to Les' strength. You gotta' hand it to Frank. If he won (and he did do well) it would have been a BIG victory - beating Le in stand up.
Don't get me wrong I think Frank pulls it out if the injury doesn't occur, but give Cung credit he showed excellen takedown defense making it dangerous for Frank to shoot.
