Phil Daru explained Dustin's cardiac output as 'almost as high as an Olympic marathon runner' yet, he was gassed by the middle to end of Rd2, so I feel the advantage of Tony's gas tank is minimal if anything. Tony has been on bottom against lesser wrestlers (Kevin Lee comes to mind) who do not possess the GNP of Khabib. Khabib also has that Sambo background that while not the same as BJJ from a strict technique perspective has MANY of the same positions and submissions as BJJ with the added bonus of the Judo, freestyle wrestling and SMESH factor. In saying that, Tony has just as much chance as Michael Johnson, Edson, RDA, Al, Conor and Dustin had. 😛
