NBA Notebook: Four theories on why the Celtics have waited to use their disabled player exception

Bob DeChiara/USA TODAY Sports

The Celtics injury ward was pretty crowded during the month of December, and those various absences were further compounded by the busiest stretch of the season for the green (eight games in 12 days).

The injury situation and some of Boston’s latest struggles (5-5 over last ten games) would seem to create a sense of urgency to use the team’s disabled player exception (worth $8.4 million) or at least fill the final roster spot with a veteran’s minimum contract (leaving the DPE intact for later use). However, Danny Ainge and his staff have stayed quiet to this point, electing to stand pat for the first three months of the year despite being down to ten healthy players on the 15-man roster on Thursday night in New York.

Why has Ainge been content to watch and wait to this point? A few theories on why we haven’t seen any roster additions just yet.
