Fastest laps, pole positions, passing ability, wind/rain driving ability, wins/placing, and many more. Michael Jordan is agreed by most to have been the greatest basketball player of his era, but he was not the best three point shorter, nor the best passer or shot blocker. But he was sitll the greatest. In the case of Schumacher, he dominates almost every stat there is. Period. The fans(polls) say Schumacher was/is the best and tbe statistics back them up. It doesn't get any more solid of a lock on being called the "greatest" than that. Now stop with your nonesense, all of you. Grow up.
