PONTE VEDRA BEACH, Fla. — From his perch in the television tower, David Duval believed he could see inside Tiger Woods’s head on Thursday at the Players Championship. “It looks like he’s thinking about every position through the entire golf swing,” said Duval, who twice supplanted Woods at No. 1 in 1999 for a total of 15 weeks. “That has handcuffed him both physically and between the ears.”
