Marc Stein:
The Celtics, to no one's surprise, did not trade Grant Williams. Making minor tweaks was the understandable preference for the defending Eastern Conference champions when they ranked as the league's only team with a win total in the 40s entering Monday's play. Yet rumbles persist that various teams are monitoring the situation and curious about Williams’ future there. Williams is poised to become a restricted free agent this summer and said to be seeking a contract in the Keldon Johnson-in-San Antonio, $20-million-annually range.
