"The more you can do, the more jobs that you can fill, whether it's in the defense or special teams, the better your team is going to be and the more value you're going to have to the roster," O'Brien said.

Defensive coordinator Romeo Crennel has been creative in deploying his players in many different spots. As an example, outside linebacker Whitney Mercilus has lined up over the center, over a tackle, and even gone downfield in coverage.

Jackson's capable of playing multiple spots as well, and explained the challenge of working some at safety.

"Switching my mind to the things that need to be done when playing that position," Jackson said. "Whether it's technique, or making the calls, or trying to put guys in the right spot. Before when I was playing corner, you were waiting to get the call. But now, playing safety you have to give the call."
