Felix is the better overall fighter ,but I reckon Benn would hit him fast and hard .Felix never recover s and Nigel beats him in to submission .Benn by 6 I predict.
Benn. Early as in 1 or 2 rounds. No time for Felix to warm up or get started. Trinidad would not go 4 rounds combined against Been & McClellan. And he sure isn't killing say 90 seconds to get to the bell against either guy.
Benn was too strong for Felix.. If Felix can hold on and get into the 4th round or so that is different.. Sort of like had Barkley been able to survive.
Benn was the harder puncher at 160 and the natural middleweight. I think Benn would be on top of him from the opening bell. If he got careless, Trinidad could hurt him but not sure Trinidad's chin would hold up under the intense pressure. Benn inside 5.
