Tyson vs Wilder would be a replay of the Carl Williams fight, in all honesty. Minus the early stoppage.
Difficult... I think AJ will go a few rounds with Tyson.... Can Wilder fight off the backfoot? Foreman is going to come out pushing him around, those uppercut he got Norton/Frazier with would decapitate Wilder.... actually not that difficult easy 74 Foreman...
If By "Mismatch" You Mean Get KO'ed EARLIER, REED'll Take Tyson vs AJ...Wilder Gets Thoroughly Dominated, No Question, But He Lasts More Rounds in REED's Opinion... REED
