I don't see why not! We've benched a player (Bruce Carter) this season that has made three times as many plays than Carr. Carter doesn't deserve half the grief he gets with Carr playing on the same unit. I'd have no problem with Scan shadowing their #1 and Moore on the other side. I'd still use Carr in the nickel but he'd have to earn his PT just like Carter if they are going to be consistent.
