Just rewatched the finish (on FIGHTPASS!!!). It really wasn't that bad, imo. Tito was initially defending himself well- or at least trying to- before removing his legz from the equation. He had his legs in play before caving in to Chuck's powerful punches. He turned over, covered up, and waited.
It was actually a valiant effort on Tito's part. His grittiest performance, aside from. the Vitor fight....
