does anyone else think jean pascal was drained?

so what do you think? i watched the fight with jean pascal vs froch and pascal looked a little fatigued, a little slow and his reflexes were not quite there. i watched the fight between diaconu and pascal straight after and a few rounds in the difference was noticeable. pascal looked much sharper, his movements looked quicker and i dont think it was a case of his opponent making him look quicker. looking at his weight at previous fights (froch, pittman, norman, camou) shows that pascal was always a 12 half stone guy squeezing into a 12st frame. vs froch his weight was 167 and three quarters, vs pittman it was a shade over 170, vs pittman he was 167, vs camou it was 172. so do you think pascal was weight drained vs froch or am i just discrediting what was a very good win for the cobra??
