Everyone's making a big deal about Ngannou's improved tdd, but do people realize he defended Stipes first three td attempts in the first fight and only started to get taken down after he started to gas and get sloppy? The first td Stipe got in the first fight was a double leg where Ngannou got close to Stipe and Stipe was able to duck underneath his punch and go for a double leg. I think early in the first fight Ngannou would've been able to defend that same td attempt that Stipe went for in the second fight where he had to reach a long way to try and grab a single when Ngannou was balanced.
The issue for Stipe in the second fight was that Ngannou was fighting in a way where he wasn't going to gas early and he wasn't going to give Stipe easy opportunities for td's. Maybe Stipe would've lasted long enough for Ngannou to start gassing had he not run at Ngannou with his hands down after hitting him with that counter. The other option for Stipe was to take more risk and be more aggressive and force Ngannou to expend more energy and try and draw out counter punches that he could try and time and duck underneath from close range.
