Three quick rough reasons that were the primary causes of Barao's failure last night 1. Dillashaw stayed outside at kickboxing range Unlike the majority of Barao's opponents Dillashaw stayed all the way out at kickboxing range and hopped in an out of range to deliver quick shots with his hands. This frustrated Barao as he couldn't establish the jab like he normally does against stationary opponents who opt to stay in boxing range against him. Coincidentally the major mistake Faber made against Barao was staying right inside boxing range and allowing Barao to freely establish the jab. Against Dillashaw Barao attempted round kicks without any set ups due to this different range. Roundkicks are proper for that range however leading round kicks do not land as quickly as straight strikes and are a little easier to see coming. Dillashaw's footwork allowed him to avoid them simply by shuffling back a step. What Barao needed to do was use straight kicks and stepping jabs as his lead strikes as those are a little bit faster and would've landed. Pederneiras warned him of this but Barao paid him no mind. 2. Dillashaw switched southpaw to land power kicks and straight lefts Outside of the fluke overhand Dillashaw landed in the first the first and with the exception of the occasional uppercut the majority of Dillashaw's landed power strikes were straight lefts, left high kicks, and speed right hooks. The southpaw stance provides a different guard and different pace of stand up fight that allows power strikes to be more easily landed and lessens the value of the jab. The majority of strikes Dillashaw landed were power strikes off his left side while taking the outside angle against Barao. Barao was taken by surprise and was unable to adapt to the sporadic southpaw striking demonstrated by Dillashaw. 3. Barao ignored his corner's advice Pederneiras advised Barao multiple times to stick to straight punches and straight kicks. This advice was given because Dillashaw was constantly on the outside in kickboxing range as opposed to the more common boxing range. Early in round 2 Barao tentatively threw a few push kicks and had the most success he had all fight. Unfortunately for reasons unknown he completely stopped throwing straight kicks and instead started throwing round kicks. While round kicks are nice they are easy to counter off of and do not land often without being set up with straight strikes. Dillashaw abused this and landed good counters off of failed kicks. I would provide gifs to illustrate these points but I have no idea where to find them.
