I think Littleton and Kiser could complement each other. Littleton seems like he'd be better in coverage, as a rush LB, etc. For now at least Kiser is a two-down run defender. So I think both could have roles. Like Ebukam a year ago I would guess that Kiser's reps increase somewhat as the season progresses. And who knows, maybe at some point Littleton and Kiser are playing inside together in some situations.
