If Roberts grabs the Suzuki by the balls and starts winning, I'll eat my words. I, and I can only speak for myself, am not counting Robers out due to one race. He won the championship last year with consistent finishes, and it certainly worked for him. I still root for the hare, though, not the tortoise.
Winning races is what makes a championship in my mind. Coming in consistently in the top five may garner the title, but it also comes with the ho-hum legacy that he has, though he is still young. We'll see if he can do it again.
