Quentin Grimes has been a revelation since joining the Sixers at the trade deadline, but his ascension does present the front office with a few good problems.

Quentin Grimes scored 35 points, including 17 in the fourth quarter, for the 76ers (22-42), who have lost four of five. Dallas sent Grimes to Philadelphia in exchange for Caleb Martin last month. Risacher’s follow-up, two-handed jam helped the Hawks close the first half strong for a 66-57 lead at the break.
