"He could fall down the stairs tonight too, but he still isn't signing that contract. "
Much better chance that he gets hurt in the course o pitching and practicing during a 200+ day baseball season, then of him falling down the stairs. In 2011 he tore his plant fascia last year he tore a muscle in his abdomen, he was able to play through those but I am sure it he is very weary that the next injury he gets he might not be able to play through.
