Sam Hornish is to replace Ambrose in the number 9 Richard Petty Motorsport car for 2015. Why would Petty pick such a ho hum driver ? I would rather see Petty put Grant Enfinger in the number 9 car for 2015. Grant has shown he knows how to win races and would put the number 9 up front. I have seen Grant race and he is as good as Jeff Gordon or Joey Logano were when they were in their early years of racing. Grant has proven he can with Ford race cars.
