Huge fight. Cain is good but JDS is better. JDS will out strike Cain on the feet avoid take downs and knock him out in round 2. Watch ! And I can't wait !
To make the assessment that his stamina is shit or that Cain will win? I think cain's stamina cant be questioned. Its not good.
I think Cain is the safer bet. JDS has pretty bad cardio issues and his ground game is a question mark. MMA is pretty unpredictable though, and let's not forget that a few fights back Cheick Kongo had Velasquez on queer street 2 or 3 times in their fight.
His one loss is by Sub. I'd take Cain or Lesnar over JDS. Both will be able to take him down and keep him there. They are worlds better when it comes to wrestling. Cain by yet another GNP stoppage.
