Did Groves suffer the Spinks Jinx?

I didn't see the fight live, but it felt like Groves was so confident and really playing up his :15 in the spotlight with the entrance and the way he spoke to Froch. It reminded me of Spinks vs Judah. Spinks came into the rematch at home seemingly feeling invincible. Now it's very possible that this could simply be a thing where he was excited and doing his job. I think he has a bright future, but Froch has always shown that it isn't his coordination or the way he throws punches that gives him success. It's that he doesn't care about how he looks in the ring, just in his will to win however he can. Do you think Groves really felt he was too much for Froch? Or he was simply doing his job and trying to make a name for himself?
