MADISON, Wisc. -- Chris Orr stood awkwardly in a sterile office surrounded by a few unfamiliar, hard plastic machines as a spinal specialist poked at his neck. It was early January, and Wisconsin's middle linebacker was as healthy as he had been in months.
A couple weeks earlier, Orr started running for the first time since tearing his ACL on the first play of the first game of his sophomore season. The knee surgery that fall was the first on his right leg. A year earlier, team doctors had used a minor procedure to remove an infection from the other one.
