I'm probably in a minority of one here, but... I thought it was a really boring victory. Yes, Cancellara is strong, but that group of 8 handed it to him on a plate. Hammond and Flecha had a stab but they were half-hearted attempts. The usual Paris-Roubaix factors (crashes, mechanicals, mud, cobbles, track sprints) didn't seem to come in to play - it might as well have been a transition stage in the Tour.
But to be fair to Cancellara - he was the strongest rider by far, so well done.
