"I went through spring and summer without any injuries, no problems," he said. Murray admits his goal has always been to rush for 2,000 yards, something no Sooner running back has ever accomplished. Adrian Peterson came closest with 1,925 yards in 2004. But if OU's offensive line improves and Murray can remain healthy, that goal might not be a pipe dream. "We anticipate him having a really big year for us," coach Bob Stoops said during Big 12 Media Days last week. "We're hoping ... similar to a guy like Adrian Peterson, that kind of opportunity to run the ball or have his hands on the ball that number of times." Murray has dedicated this offseason to preparing for that kind of workload. Instead of going out for fast food, he's been grilling chicken and vegetables in olive oil at home. He's also spent countless hours stretching out his muscles. He's even taken a yoga class.
