Groves-Froch makes perfect sense.*

Groves was scheduled to fight Stieglitz for the WBO title before pulling out through injury. He is also rated no.6 by The Ring magazine (i know stop laughing). So he is already considered "world-class" by not just certain alphabet organisations but independent rankings too.

That means he's a perfectly valid opponent for Froch (who has already fought most of the top ten).

((*I like Groves but i'd love to see FRoch smash these young Warren fighters to bits... which is obviously never gonna happen in a million))
