hes ogt more track time then others such as Rossi there but it still comes down to being better then the others.....is he the best.. No, will he be some day..? Who knows. To Top Rossi and Lawson hes got some titles and races to go.. about 2 careers worth.
Hayden may have more track time then Rossi and Lawson there...but I don't think it matters to much to Rossi what track he is on. If he wants it bad enough and he always does...he'll bet Hayden like he has in the past. Hayden a great rider but Rossi just outrides him on any track for the most part.
