"I think his approach has changed a lot from last year. He's looking inside himself a lot more," Michael Andretti said Wednesday. "He's improved in a lot of areas in his driving that he worked really hard in over the winter. What he did was a very difficult thing, to change your driving style. It's still not totally natural to him, but he's done a wonderful job and he's still got room to improve. When he does, he's going to be up front in all the races."
