Mack pinch-hit for the vacationing SI.com’s Peter King in today’s Monday Morning Quarterback, and mostly expressed his excitement about joining a veteran-laden Raiders defense.

The pass-rushing specialist made it clear he has a lot to learn, but said he thinks the Raiders plan to use him at multiple spots on the field.
