Rossi the GOAT, well may be or may be not, he has not had a usable bike since joining Ducati, rule changes, and other manufacturers catching up.
To see if he is the GOAT, he needs to race the IOM TT, he has the skill, and he has been there to spectate, to surpass AGO, Hailwood, Dunlop as some of the greatest road racers of all time.
Can you imaging Rossi on Glen Clutchery Road, with Mcguiness, Dunlop, Martin etc, and full factory bikes like in the 80's and early 90's.
what a crowd puller that would be.
and just as a point of conjecture Stoner at the IOM TT, i dont think he has the balls, bit like comparing football players to rugby players, unless it is perfect and smooth all he does is winge.
Rossi at the TT, i would love it, cause he can and could win there.
