A couple powderpuff, Fancy Dans. 15 rounds, if that matters. Make your pick and state your case (preferably by using fights in their respective resumes).
Day before weigh in or same day? Edited to add: The only guy I can think of who Steele fight who is remotely similar to McClellan is Hostak which was a bad blowout. He was injured though. Hmmm...
Steele brought great footwork, elite level two-handed power and a stout chin to the ring. Discounting his post-injury record, he was pretty unbeatable at a time when the division was arguably it's deepest. He beat: Apostoli, Garcia, Risko three times, Barth, Kreiger, Overlin, Jones twice, Dundee and Lesnevich. That's a deeper win column than McClellan had (tho admittedly his career was cut short, too).
Steele can be argued to be a top ten great at middle, a very historically deep division. Gerald was huge at the weight and could really punch, but he lost against guys who weren't even world class on the way up. He could be defused, out boxed, beaten. People talk about him like he went on a several year tear through the divisions best and left a trail of battered fighters in his wake. He didn't really prove much in terms of greatness or overall ability despite his highlight reel knockouts.
Steele is one of the very best fighters I've ever seen. The way he destroyed world class opposition with such ease is incredible. The loss to Apostoli is an issue but he's also one of the best I've ever seen. G-,Man hits really hard but it's tough gauging how good he is with such a short resume. Ultimately, Benn managed to survive a war with him and win late on so I've no doubt Steele does the same.
Contributing quality stuff should be something all real fans aim to do. If you're bothering enough to register on a site dedicated to boxing, why not? If no one reminisces and talks about the past of the sport, how's it going to be remembered or meaningful? It'd be a shame.
