Let's place both of these men in the same ring at the age of 37, which would be Sanders who sparked Wlad in 2003 and Vitali who reached 37 in 2008 and beat Sam Peter... Of course Vitali was coming back after a long layoff, but then again Sanders wasn't fighting terribly often either. Anything different under this scenario?
Sanders is an ATG caliber southPaw when in shape and focussed. He gives any heavy in history a hard night
If he was in better shape than for just a few rounds, he gives Vit a great fight, but at the end of the day it's still Vit by TKO
