Last season, had to be a bit of a relief for Ernie Grunfeld. While other GM's had to try and shuffle rosters depending on injuries, D-League callups, and the like, Grunfeld roster set-up was quite simple. The Wizards only carried 13 players on the roster (except for Mike Wilks' two week ) and Etan Thomas was on the Inactive list all season, so Ernie was left with 12 players to fill 12 spots on the active roster
Now with Etan getting healthy, as well as the addition of JaVale McGee, the Wizards have 14 players to fit into 12 spots on the active roster. In other words, two players are going to have to get used to watching the game from the bench in suits. In my mind, the only rational choices for the inactive list are JaVale McGee and Oleksiy Pecherov. While part of the reason I say that is because they're the 13th and 14th best players on the team, the more important factor in my reasoning is a valuable asset that we can use to our advantage like never before: the D-League.
The D-League was made for players like McGee and O-Pec who need experience to help realize their potential. Players in their first 2 years (a qualification both players meet) can be optioned down 3 times in a season, so we can let McGee and Pech get playing time that they need and wouldn't get in Washington and still have them available for when/if someone gets injured. If there's a drawback in letting those two develop their games in Dakota, I haven't seen it.
The Wizards haven't used the D-League a lot in previous seasons, partly because of a lack of prospects and partly because of a lack of warm bodies. Now that both of those issues have been resolved (for now), there's no reason why we shouldn't be using of the Developmental League to help develop our players this season.
