Honestly - who really cares? F1 evolves as time goes on. These same discussions happened with Moss, Hill, Stewart, Fittipaldi, and the list goes on. Obviously, this type of discussion only honors those drivers (like Schumacher) who have achieved so much.
We are all happy that Schumacher was able to achieve so much success and then retire in good health. I wish him well and look forward to this year's F1 season. Let's all enjoy what we have instead of looking at the past or the maybes of the future.
