What should they do? They should sign ....!!
My thoughts are simple. The C's dont have the cap space to just out right sign Terry, Mayo, Gordon, Hibbert ...etc. So i would look into using the players they have the cap holds on as S&Ts..
example Kristic is technically a celtic still. Ther Raptors
want to move Calderon...so... Calderon is getting 9 million for 2 more years, he would be a great back up for rondo, low turnovers, high % at the free throw line and 3 point arc. They can get a big, and the celtics dont have to resign dooling & pietrus.
Be respectful and keep it clean. Thanks.
