As for the bad stoppage, that was on Lawler for letting his arm go limp while getting choked. You see guys all the time actively letting the ref know they're okay to continue. Everyone in that arena thought Lawler was out. And yes, Askren got caught and KO'd. Anyone can get caught. But that's not the point.
The point is Bo quit when he faced relatively mild adversity, while Askren battled back after getting it handed to him. Bo is more naturally gifted than Ben, but Ben was a legitimate fighter who didn't look for a way out.
