The facts as I see tham are:

George Groves beat up the No 2 World Supermiddleweight, cameras don't lie.
George Groves is now out of contract with Eddie Hearn.
Eddie Hearn during the first round saw George Groves taking 2 world titles away from his stable.
E***e H***n passed a word to some officials during the fight
Eddie Hearn has convinced George Groves to campaign for a rematch (with his media help and obviously he will promote it)
Carl Froch is pissed off, because he never actually put a foot wrong, just fought his normal fight, best efforts etc. but not good enough, and is being 'forced' into a rematch that he knows he will probably lose.
As I have said before Groves should tell Hearn to poke it, get an American promoter and go for Ward/Dirrell etc.
