Till now, i still see Rossi above them all, in both performance on track and results.
I think that is a fair assesment, if you take any one of those riders motogp careers and compare it to Rossi over the same timescale Rossi has been better and achieved more. However you can also see that his advantage is getting smaller, his most recent world title was his hardest and this season he was 3rd of those 4 riders. That's what makes this such an exciting and fascinating time.
