James Stewart on Ricky Carmichael and moving to the premier class
Stewart had something to prove that went beyond racing motorcycles, but that need to win made him ride over his head all too often. You can't win if you crash, regardless of how fast you can ride a few laps at a time. Carmichael was fast and consistent so outpacing him for a few laps wasn't going to cut it. Stewart kind of started acting weird anyway, probably because of the fame, money, injuries and failure to secure more championships. Luckily, he settled down and is what we see today.
