Daaaammmmmmnnnnn!!! Tiger would get the better of the bout in close exchanges, even though the G-Man had better one shot KO power. Inside, Tiger's banging skills and stockier frame would be too much for McClellan's lankier frame, which was better for timing and landing a big punch before letting his hands go on a hurt opponent. Both had great chins and wills though, but I don't see McClellan just outboxing him, he wasn't that type of fighter. Therefore I feel this is a bad matchup for him. Tiger by UD, maybe TKO if McClellan tires himself out in early exchanges, or gets dropped early.
As great as his chin was, Tiger was human. Actually I see Tiger wearing down around the 6th or 7th, and getting finished by a three punch combination.
So McClellan was not human then? You gave nothing here, just how you think Tiger would wind down despite how outbrawling every pressure fighter and puncher he ever faced.
