WATKINS GLEN, N.Y. — Kevin Harvick had the luxury of racing with abandon.
So did Joey Logano.
Kyle Busch really didn’t. But he did anyway, until it wasn’t the wise move anymore. He still finished second.
The scary thought for Busch’s competitors approaching the final four regular-season races and entering the Chase for the Sprint Cup is that he really, officially, can go full-bore now. Because after winning four races since his return from a broken foot and leg and pressing extraordinarily hard to add another Sunday at Watkins Glen International, Busch finding another level would be threatening to anyone else’s championship hopes.
