When you are rolling along the way the Celtics are, it’s hard to imagine a ton of thought is being put into shaking up the roster.

But when it comes to change, president of basketball operations Danny Ainge has proven himself to be open to it regardless of how the team is performing at that time.

Which is why the Celtics are very much open to using the Disabled Player Exception (DPE) they were granted by the NBA for Gordon Hayward’s left ankle injury – possibly this week.

Because if the Celtics want to utilize the $8.4 million exception to acquire a player and use him in a subsequent deal, they have to do it by Friday.

Utilizing the exception, the largest ever granted to an NBA team, would not be a major issue for the Celtics, who have an open roster spot available to sign or trade for a player without having to do any roster shuffling.

Boston has 16 players under contract, but only 14 have fully guaranteed contracts. The league maximum for guaranteed contracts is 15. Boston signed rookies Kadeem Allen and Jabari Bird to two-way contracts, which do not count against a team’s guaranteed contract total.
