JMM's win over Pac has rocketed him to the top of the welters but apart from Pac who he has had plenty of practice against, would he look good vs anyone else? he looked rubbish in he fight against that Russian who went 12 with him and we cant include that guy who took a dive in round 1 so Marquez is still unproven at 147 IMO.
Mosley is washed up but styles make fights. A smaller Mexican fighter might suit him at this stage and hes always had a reliable chin. Depends if Shane shows up with any ambition or not or if he is just cashing in for the last few years. If he does its a winnable fight
