SANTA CLARA, Calif. -- Patrick Willis said last week he was hopeful to play after suffusing a groin injury in Week 3, but caution won out.This week, it sounds as if Willis truly has a chance to play."Last week, I really tried to push it to go and it just wasn't all the way there," Willis said Thursday. "What I didn't want to do was lie to myself and teammates and not give all of myself. Me and the training staff felt it was the right approach.
