By Mark Lamport-Stokes CHASKA, Minnesota (Reuters) - Phil Mickelson is known for having a theory about almost anything and he says that the United States have been handicapped at the Ryder Cup over the last two decades by poor preparation. This week at Hazeltine the U.S. will bid to end a run of eight losses to Europe in the past 10 editions and Mickelson is excited about the prospect of a new chapter being established under captain Davis Love III with the players fully engaged. "This is the foundation week for us," Mickelson, who has competed in 10 Ryder Cups, told reporters on Wednesday before heading off for team practice with Rickie Fowler, Brooks Koepka and Jimmy Walker.
