of course he isnt coming back, he's done. But man he could make a ton of money coming back now with Brock about to come back. If Viacom got Brock they'd go hard after Fedor, if UFC didnt get Brock they'd offer Fedor a truckload of money to keep Viacom from getting him. If UFC got Brock they'd probably want Fedor for that fight and same with Bellator, if they dont get Brock they'd want to keep UFC from getting Fedor.
Both guys could play Viacom/UFC off each other and cash in. Thats alot of money to leave on the table, you can only make that money now, when you are really too old and cant fight anymore there is no getting that money back.
But he seems ok with not fighting and probably has a good amount of money and doesnt need it. I just dont think I could turn down that kind of money, dont care how much you have its never enough.
