Old George vs Smokin Joe

We all know what happened when Big George at his best met Joe Frazier in Kingston, and it's hard to imagine any fight between the two going any other way. Stylistically Foreman always beats Frazier, but do styles define fights to the extent that Foreman at the age he KO'd Moorer could dominate, say, the Joe Frazier that defeated Ali in 71.

I'm in two minds about it. If Foreman isn't quick enough off the mark to blast out the slow starting Frazier then it's hard to see his slow pace keeping up with the relentless pressure of Frazier for the whole fight without meeting some smokin left hooks.
