Damn right Brock Lesnar will be tested Saturday night in Anaheim during the next UFC PPV. Cain Velásquez is fighting for a cause,or so it seems, his heritage, but more importantly Velásquez is a great athlete who has won at every level of amateur and professional competition. Plus, any heavyweight in UFC is always only one punch away from ending his night's work. I see Lesnar winning Saturday but not without having a great night of stand up defense and using his size advantage appropriately. Lesnar being already at 265 and shredded is a scary thought for any human being who has to deal with the baddest man in MMA.Jim Ross gives his thoughts on the main event of UFC 121 this Saturday night.
