Been seeing this a lot passed few days...i dont see why he would as he is already his own boss...maybe a joint venture?
I have scratched my head over this one a bit myself. While I can certainly see why Roc would want Cotto, I have a harder time understanding what Cotto would get from Roc. Cotto promotions already involved in big deals / join ventures, so while I suppose its possible they are doing joint something it seems like it would be complicated from business end to iron out. Too many cooks in the kitchen, but who knows?
Maybe they will combine promotion companies and Cotto will be a partner in the business, like GBP was doing with BHop and Mosley.
