Froch clearly isn't comfortable in these confrontations. You can tell by his glazy eyes and he's obviously trying really hard to look cool about everything. As strange as it seems, Groves' biggest worry is Complacency. Even though he gave Froch a lesson last time, he DID tire and he DID LOSE. I hope Groves realises this and trains harder and gets even fitter , because if he can last the 12 rounds (although it may not go that far) he cannot lose. I worry that if he believes everything he says, mentally he might take the foot off the pedal. As for Froch taking Groves lightly........Rubbish! Are you telling me a World Champion takes an opponent lightly? Especially someone he detests.
Also, there's more chance of a guy in his mid 20's showing improvement than a 36 year old.
I'm gonna trust Groves to be professional and say he finishes Froch in the 10th after Froch has taken a lot of punishment.
I actually worry about Froch because it's the relentless beating that does damage rather than a clean knockout. I hope I'm wrong about that part.
