This is a tough call........ I don't think Liston's jab would be a factor. Frazier had too much head movement for Liston to use his jab effectively. And I'm not sure Liston had enough one punch power to do to Frazier what Foreman did. Liston tended to wilt when the other boxer was not afraid of him, and Frazier feared nobody. Also, there's not that much difference in size (Frazier around 6", Liston 6"1"). Unless Liston really lands some haymakers early in the fight, I see Frazier winning a split decision.
