We have never been known for endurance. There are other factors though. We have some real muscle bound guys and more muscle requires more oxygen. So guys like BC and Mekhi they require more gas than the average guy. Someone like DMF is carrying more muscle than he ever has and is wrestling heavier competition which is to be expected. Then you have guys like ZZ who are probably cutting a heck of a lot of weight.

Where I pause and think you may have a point worth looking into is looking at Blees. His bread and butter last year was outlasting guys and beating them in the third period or OT.
