I think Foster beats Tarver and Johnson, and loses a wide UD to a prime Jones. Theres nothing in Jones prime history to lead me to believe he gets KOd.
Foster is a heavyweight walking around as a lightheavyweight. He would have 4 inches in height and about 4 inches in reach advantages over Jones. Plus one punch knockout power in either hand. He is not John "The Quietman" Ruiz. Foster was a mean mofo that loved to see people bouncing around on the canvas, especially out-gunned lightheavies.
Foster was a heavyweight? Is that why both Ali and Frazier had over forty pounds on him after he tried to bulk up to face them?
Foster would have beat most Light Heavies in their prime, including Jones. He was patient, and Jones did make mistakes. Because of this, I believe Foster would have caught Jones and knocked him out.
Foster was patient later in his career... He was a lot more active earlier in his career. Became a stalker later on from what I've seen.
What I was trying to say is he brings heavyweight power and diminsions to the Lightheavyweight Division. We had a tall, skinny kid nickname Spider in high school with us. A big, American football stud tried to pick on him one day, so Spider destroyed him. He might have been skinny, but leverage and natural strength turned the Spiderman into someone the football player didn't want to see again.
