After not riding like his usual self at Laguna Seca (probably didn't fancy hitting those concrete barriers) and getting beat by his team mate and the new kid on the block Hayden, Rossi won't want either of them getting any more confident and will assert his authority over both of them (IMO).
Hayden??? no chance.... top 5 maybe, but he hasn't shown that much in all his time in MotoGP, Laguna was his home race and knew the track like the back of his hand and fair play to him.
I'll tip Edwards also, Melandri will be up there, be nice if the Ducati's could get a podium, and see Troy running at the front at a circuit he knows well.
