Celtics exercise team options on Marcus Smart and Terry Rozier

The Celtics made two moves Monday night that give insight into general manager Danny Ainge’s vision for the future, exercising the 2017-18 options on the contracts of Marcus Smart and Terry Rozier.

In addition, Ainge declined to pick up the fourth year option on Smart’s fellow draftee James Young, and didn’t extend Kelly Olynyk as other teams hurried to extend their ’13 draft picks before the midnight deadline last night.
