PHILADELPHIA (CBS) – While there is plenty of news off the field, the Philadelphia Eagles are keeping busy on the field at Lehigh University.

Juan Castillo in his first year as defensive coordinator, and he has a simple philosophy to go with his coaching style.

“We’re teachers and every day, we’re going to get better at certain things. Every coach has what we call a “daily must,” something they’re going to work on every day and going to improve,” Castillo explained.

Castillo switched to the defensive side after serving as the Eagles offensive line coach, but he believes the switch will be a smooth transition.
