There is no doubt that Haye could be good for boxing. I don't think boxing needs him, but with the only 2 remaining marquee stars to the casual fan, Floyd Mayweather & Manny Pacquiao, probably having at most five fights left between them, boxing is going to need stars to take over. I think Haye can offer that, I struggle to see anyone else who can on a global level apart from Kelly Pavlik. The general public are generally only interested from 135 upwards, so I think that rules out Juanma for a while, who is already arguably the biggest star in Puerto Rico (ie more popular than Cotto, not a better fighter yet). I think there will be a lot of guys who are stars but in their own countries.
