Tony Hawk was the best skateboarder of all time. He is the Michael Jordan or Tiger Woods of his sport. Not just the best, but iconically so.Hawk won 73 of the 103 pro contests he entered. His video games sold 30 million copies and grossed $1.7 billion. Six Flags named a rollercoaster after him.I was never into skateboarding. But like millions of others I remember Tony Hawk for one thing: Landing a 900 at the 1999 X Games.
