I think this is a bettter example of how sponsors are running the show these days. Sponsors want the next hot driver. So they go out and pick up on these young guys. If things don't work out quickly they are out the door and the next guy is in. It's more about a drivers marketing skills than his driving skills.

This can swing the otherway as well. There is really no on track reason Michael Waltrip should still be racing, but NAPA likes him becuase he is a good, personable spoksman.
