I don't think Teixeira stands a chance against Machida. Teixeira doesn't seem to be improving anymore. His striking is really nothing good to speak of. He keeps marching forward and fires that right hand. I'm sure Machida will be able to exploit that.
Barao vs Aldo is a much better fight but I believe Aldo takes it. Barao has a good jab but Aldo has an equal reach, and surely Aldo ain't gonna let Barao jab him all night. Aldo also throws better combinations, much better in fact. Barao seems to get hit a lot when he goes for a combination.
