Bob Foster was a monster at lightheavyweight. I don't however recall him being very successful when he ventured up to fight heavyweights. How in the world would he be able to compete with Jack Dempsey? Dempsey would flatten him without a doubt.
Foster was tall and was skinny like a bean-pole and didn't look to be that muscular or strong as compared to the ripped Dempsey phsique.
Jack hit too hard for Bob but Jack would feel a few shots from the string bean..Foster a natural Light heavy was too Frail to Survive JD...Dempsey in about 2
