The PGA Tour is unquestionably the strongest professional golf tour in the world.
However, some of the strongest players in the world have declined membership. Lee Westwood, ranked second in the world, Rory McIlroy, ranked third, and Matin Kaymer, ranked sixth, all declined membership for the 2011 season.
McIlroy has taken up membership for the 2012 season, but his preliminary schedule leaves much to desire.
Besides these top three players, Matteo Manassero and Alvaro Quiros could spark some intrigue on the PGA Tour.
