He's fucked, although i think they are going to give him only two years... In the eyes of fans his legacy is completely destroyed and irrelevant now... Yes, they are all on drugs but it seems that JBJ was going overboard, steroids, anti-estrogens, testosterone's anomalies, cocaine and such, Cormier never had strange results and odd levels in his testings, as far as i remember...
In my opinion guys like Overeem, Miocic, Velasquez, JDS, Werdum, and few other top heavies would've beat him, there's a reason JBJ always stayed at 205, where he could count on massive size and reach advantages...
