I doubt Woodley's hips hitting him bothered a veteran of like 40 MMA fights all that much, but the way he was stuffing the TDs without getting out of position to strike made every attempt very dangerous for Maia. Almost every time he shot TW was ready with the right underhook and it meant that he didn't have to turn his back to limp leg or fully sprawl, which in turn meant that on the exit Maia was a sitting duck for half a second. Well, that's way too long against someone with power like Woodley's, and I think that fear of getting cracked off the failed TD was a big part (along with energy management) or what kept Maia away. Look how cagey he was in terms of trying to back Tyron up to the fence and clinch with him, which is usually his best method of getting TDs (not that power double he repeatedly went to here); that was almost certainly because we was worried that getting into the pocket was going to get him rocked, and he was probably right.
This fight sucked for two reasons: the first is that Maia, upon figuring out he couldn't get Woodley down without significant risk, basically chose not to take that risk and kept waiting for Woodley to over commit to where he wouldn't be able to keep Maia off his hips on a reactive shot. The second reason is that Woodley, knowing the only way he was going to get taken down was by over committing and trying to finish Maia but that he could easily box him up with pot shots and win a decision chose to let Maia back him up the fence, threw a right as his feet edged the cage to scare Maia off, and then whether he landed or not he refused to follow Maia past the center of the octagon so you just ended up with the same series repeating itself over and over: Maia throws weak jabs while edging forward, TW edges back, when Tyron's back foot gets close the cage he fires a few shots and explodes forward which causes Maia to back straight up a few feet (God forbid anyone angle off in this fight), Woodley stops as Maia backs off, and Maia comes forward with probing jabs. Repeat for the middle 3 of the 5 rounds.
