After a fairly quiet NBA trade deadline by the Boston Celtics, the defending champs will now hit the buyout market to fill at least one open roster spot

The Boston Celtics surely won't be the NBA's most active team leading up to Thursday's 3 p.m. ET trade deadline. However, they can't just sit out

The Celtics do have limitations in terms of who they can sign on the buyout market. Boston is above the second apron so they aren’t allowed to sign players that were making more than the non-taxpayer midlevel exception ($12.9 million) when they were bought out.
