Well said! And let us not forget the guys who race the Isle Of Man TT and Manx GP every year- the ultimate test in motorcycling.
I am a big fan of Rossi and would never expect him to race the Island because it is seen to be too dangerous in this modern age, but we need to remember that Agostini, Read, Hailwood, Sheene etc had to race on the island as well as riding all the regular championship rounds.
For this reason I don't think we can ever make historical comparisons as to who is the best- they are all great men.
