Ravens guard John Urschel beginning work on Ph.D. at MIT this offseason

In his two seasons with the Ravens, John Urschel has started at three positions -- left guard, center, and right guard. Now, he's back in school trying to earn a third degree. As a collegiate standout at Penn State, Urschel earned his bachelor's degree and master's degree in math there, and was working on a second master's in math education when he was a fifth-year senior. That meant teaching classes on top of his football workload. But the balance was never an issue for Urschel, one he said in his first minicamp with the Ravens was one he enjoyed.
