I'm gonna go with a Holmes competitive UD. I won't rule out Lennox scoring a flash ko, but I think the odds favor a Holmes decision more so.
Lewis. I don't think Holmes can hurt Lennox that badly. I do think Lewis can hurt Holmes badly. Lewis UD 12.
I'd go with Larry, but not with great confidence. I think he was more fluid, faster, more agile, and had a snappier/quicker jab than Lennox. I'm kind of seeing Lennox having more trouble getting his shots off than Holmes and getting beat to the punch, out-jabbed, and out-manuvered.
I will take Holmes because he has a better work rate and a better jab. Holmes would probably have to get off the floor to get the win though...
Sorry buddy didn't mean to call it like I see it or anything. Holmes has 1000% the workrate of Lewis. Even when he was old....
