What did I just get through saying here?
Mentioning how little time they spent in regular is also saying how much time was spent in nickel and dime: an extra defensive back—it was just a little over 95% of the total snaps. It can't be said, "Will is almost always on the field" and preface that with "except when they have extra DB's" when they have extra DB's in, almost literally, all the time.
Moody played opposite MIKE, in this defense as a WILL. He took less than 50% of the snaps as compared to Anderson and Turner. (To'o To'o had over 100 more snaps than either of those two.) Hence, the WILL position isn't on the field as much.
You say you think he's going inside. Okay. I'm saying the signs point to him staying outside—SAM before JACK.
