A Boston Celtics guard is on his way to the team's Development League affiliate in Maine ... and no, it's not Rajon Rondo.

MarShon Brooks, a third-year guard who has been used sparingly all season, was assigned to the Maine Red Claws on Wednesday.

Brooks has appeared in nine games this season for the Celtics, averaging 3.2 points and 1.6 rebounds in 6.8 minutes per game.

While it is somewhat unusual for players to be sent to the D-League after having had two-plus seasons in the NBA, the move seems like the right one under current circumstances.

When training camp arrived, Brooks was among a clustered group of guards who were all vying for minutes.

In time, Brooks steadily fell further and further behind the pack to the point where he was easily the most seldom-used player on the roster.

Jordan Crawford emerged as the starting point guard. Courtney Lee has bounced back from a weak 2012-2013 to become a consistent contributor off the bench. Even rookie Phil Pressey has played his way into being a meaningful participant despite having the least amount of experience of any of the team's guards.
