This is a bit of SPOILER so dont read on if you havent seen the card yet. In the main card at least every cocky fighter lost. Kendall grove was pretty damned cocky and he lost. Kos was way cocky (GSP is going to outwrestle ME!?) IMO Crane seemed to be a bot cocky about taking the fight to the ground. Even Gonzaga seemed a bit overconfident I've noticed this a lot in the past, people who are showboating and jumping around before fights or talk a ton of shit (tito aside, he talks shit no matter what) tend to get beaten. They're trying to pump themselves up and convince themselves.
