Cardinals running back Ryan Williams told the Arizona Republic that he was more concerned about his knee than his play last season, saying he played scared. Williams came back from a torn patella tendon suffered in 2011 and wasn't ready for the physical punishment that comes with playing running back. Per the story, he got nervous when then-quarterback Kevin Kolb would call '39 toss' because it exposed his right side and his injured knee. The lack of confidence left him "pretty much scared all last year to get the ball in my hands." He added hurting his shoulder was a "blessing" because it allowed him time to get his knee feeling good. Now he says he's not scared anymore. "This is the healthiest I've felt in the past two years," Williams said. "It feels good to be able to run like myself, instinctive and not having to think about what I’m doing, just going out and doing it. I've been working real hard, so things are looking good. My stars are aligned this year."
