Seriously? Tyson is so out of shape now, Toney is actually still going to fight professionally. He is obviously not that good anymore, but he can still compete with some guys. Tyson would get owned if he stepped into the ring with any decent fighter nowadays.
In their primes it would be a great fight. I actually would pick Toney. Toney has never been knocked out, and that includes his fights well past his 40's. He is very mentally strong, has an extremely good defensive game, and is a better fighter in the later rounds than Tyson...
Half of the guys who lost to Tyson lost before they even entered the ring. James Toney wasn't afraid of anybody.
