I think Foreman would not have taken the risk of fighting the undefeated AJ. That would have been someone like a Lennox Lewis/ Riddick Bowe for him. However after AJ lost to Ruiz, he may decide to take the risk.

I think there a sufficient weaknesses in Wilder for Big George to take the risk to fight him probably losing most of the rounds hoping that Wilder will make the mistake Moorer did. I think Wilder would be too wise and just try and win by decision. Leaving a bruised and battered Foreman.

Tyson Fury would simply outbox Big George and do Ali impressions at the same time.
