CHASKA, Minn. (AP) — Dustin Johnson made an exception to his rule of never watching golf on television, only because it was the Ryder Cup. "That was the only thing I missed," Johnson said. The best player this week at Hazeltine, he was nowhere to be found two years ago at Gleneagles. Amid a published report that Johnson twice tested positive for drugs, he took a six-month break from golf to seek help for what he described as "personal challenges." That caused him to miss the PGA Championship, the entire FedEx Cup playoffs and the Ryder Cup. That now seems like a long time ago. Johnson is No.
