Well.... he was nearly 40 and did have the dubious distinction to have lost twice to a blown-up light heavyweight just before the Tyson fight.

Not saying he was totally washed up.... only that he was beyond his prime. I think his prime was late 70's early 80's.

Having said that, beating the undefeated Mercer was definitely a late career achievement.

Still...... past his prime or not..... I was elated to see Tyson tear him a new one.
