Andre Drummond
Perhaps the best fit amongst veteran free agents, Drummond immediately plugs the rebounding and depth holes the Celtics face.
The big man averaged 8.4 points and 9 rebounds in 17 minutes per game with the Chicago Bulls last season, and although his best defensive years are behind him, Drummond’s presence for the Celtics could be a great fit with Porzingis while offering important insurance at the position.
As long as he remains serviceable on defense and keeps his shot taking to a minimum, he’s worth a serious look if you’re the Celtics.
