He only has 89 starts in the Cup series. He has 222 career starts in the top 3 national series with his highlights being 6 wins in the Truck series, but he was a development driver for the top team in NASCAR (Kyle Busch Motorsports, who is an affiliate of Joe Gibbs Racing) and thus had superior equipment for 5 of those wins.
Is that uncommon?
It seems like a bad record, I just don't know anything about NASCAR
Don't know for sure, but 220 races (including the lesser series) seems a bit much without a win.
