You can't ignore weight class, it's everything. I think Ward is either past his prime or not as effective at 175, probably both. He's been a damn fine boxer, but he's not Mayweather and it's not close. Take any great fighter who maxed out at 147 and make them a light heavy while pretending they wouldn't sacrifice everything that makes them great, and they'd be a complete freak of nature, that's just how it goes.
