CHARLOTTE, N.C. (AP) -- Greg Biffle, of Vancouver, Washington, certainly didn't sound like a guy committed to Roush Fenway Racing when he blasted the faulty equipment that led to his last-place finish at Darlington Raceway.

Greg Biffle.

Biffle says all he wants is equipment to drive that stays together. He started from the pole and led 95 laps Saturday night before loose wheels, a bad vibration and a broken timing belt ended his race early.

He seemed to have the car to beat, but instead left the track still searching for his first win of the season. It was clear "The Biff" was sending a message with his biting remarks.

Just what might that message be?

Well, signing a contract extension with Roush might not be the slam dunk both sides have led everyone to believe. In fact, Biffle might finally be ready to test the free-agent market.
