Not sure why Murray doesn't "deserve" to fight Groves? He lost two tight decisions against top world-class fighters and got chinned by Golovkin (although taking him 11 rounds is worth a medal in itself).

Groves has a win over DeGale when they were novices, got ironed by Froch and lost against Jack.

Murray doesn't need to prove anything to get a fight with anyone at supermiddle. Especially someone that doesn't even have a "world" title. He's not a puncher and doesn't have the most exciting style but - barring the freak that is GGG - he's not a walkover for anyone at middle/supermiddle.
