Collins might be able to do a psychological job on him, but the evidence of their 160lbs careers suggests McClellan is a very warm favourite, and I would take him to get the job done inside eight.
Interesting fight. There’s a chance that Collins can weather the inevitable storm, and take advantage of McClellan’s weaknesses. The G-Man was 2-3 (0) in fights that went past the 5th, and Collins had great stamina and would keep coming all night long. If Collins sees the second half of the fight he probably wins. The odds are that doesn’t happen though. McClellan was the better boxer, and would inevitably land some of his heavy artillery. Collins has a great chin, but it’s Russian roulette for any middleweight taking punches from McClellan. He was also a devastating body puncher, and would be one of the middles that Collins didn’t have a size advantage over. I think Collins’ best chance would be to come in like he did against Pyatt and keep it at range. I think his fighting instincts would take over though and he’d want to prove he was the stronger man in there, which would be his undoing.
McClellan out boxes him but no way drops Collins for the count and if he can't go full leather for 12 rounds he's going to lose. I'd give it either pts to McClellan or a late tko for Collins. McClellan dominates rounds 1-5 and staggers Collins in 3rd, Collins isn't going away though and his stamina keeps him in the fight. McClellan wins rounds 6 and 7 but closer. Rounds 8-10 go either way and Collins drops McLellan in round 11 way behind on the cards.
McClellan was easier to hit, his movement ws lousey as was his head movement, if Benn could survive v g-man then Collins could and he was proven at a higher level by giving Johnson and McCalum tough rides, the version of Eubank that was outpointed twice by Collins wouyld have outboxed G-man, he was vastly overrated and Benn exposed his defense.
Real interesting matchup! I have to think on this a bit. A couple good answers I liked so far though.
