It's tough. I really want to see Schultz play, but our top 4 is currently solidified with Letang, Dumo, Daley (who has been excellent and is truly fulfilling a top 4 guy), and Maatta (who has been just up-and-down but handling big minutes pretty well despite some deficiencies). That leaves the bottom-pairing, but Pouliot has been very good since his call up, and being that he's our top D prospect and is looking NHL ready, he needs minutes.
Really the only spot he can go is in Cole's, since he's an RD anyway, but Cole seems to have learned from his benching, and is playing solid with Pouliot. Plus Pouliot+Schultz seems like a potential defensive liability, even though Pooh has been playing defensively sound.
