Thats massively short sighted. Anybody with half an unbiased view can see that hammo is something special and not just some mid pack grid filler. It why a team, a great team at that, has been build around him at the age of just 24.
The teams dont invest that sort of money into drivers according to what the read on internet message boards. They have the money to buy anybody on the face of the planet they want to fill that seat... and they've chosen Lewis. They see the telemetry and the real team mate comparisons, not the diluted results we see at races with god knows what factors influencing the outcome.
Its also rediculous to judge a driver by the amount of championships he has. The Stirling Moss story is just one example thats beaten to death. That seems to be more of a crutch that Schumacher fans hang onto to try to diminish the efforts of those taking over the mantle.
What makes Hammo special (like schumacher, like Alonso) is he's a true racer, he lives to race, and you can see it in the way he carries himself when a win slips through his fingers. He doesnt have to win 5 championships to prove he's good, he shows us every fortnight when he tries his heart out to do the best he can for himself and his team.
