Freddie Steele 160lbs, Chris Eubank 175-180lbs and Steele has the wrong style to fight a bigger man, espeecially when Eubank is very good at countering and setting up punches and is not slow at all
Unfortunately, you have some good points here. Steele was plenty crafty and athletic, and in his prime was nearing being unbeatable. I'll shade toward him but keep my wallet closed.
I'd like to see more Steele footage myself. It's certainly within the reach of a guy like Steele to beat Eubank. They have similar styles in some respects, looking to explode and blast the other guy out. If I had to guess, probably Steele on workrate.
