Lots of comments in this thread suggesting that Boonen had a bad 2010. I think that's not really accurate.
Sure he didn't win any of the big ones, but he was pretty strong. Recall that he was gaining time on the chasers in the final kms of Flanders (even while Canc was gaining time on him), and he was arguably the only one of the chasers at PR who wasn't racing for second place. Without Spartacus in either of those races (or E3), we would all be lauding another Year of Boonen over our Fresty Fresh sandwiches.
As for 2011, I'm holding out hope for Haussler, Nuyens, or Pippo to mix it up in Flanders, but I have a hard time imagining anyone staying away from a motivated Boonen/Spartacus-led chase group.
I like Hushovd or Boonen in a small bunch finish at PR--but it would be cool to see Pippo, Balan, or Canc sneak away in the final kms. (Just not the final 50.)
