Gilliam was the offensive story for the Bucks in the fourth quarter, scoring 10 of their first 12 points to pull Milwaukee within three, 72-69.

The Bucks struggled offensively in the third quarter, tying a season low by scoring eight points in the period and making just two field goals on nine attempts. The 76ers were able to overcome a four-point halftime deficit to pull ahead by six, 62-56, after three quarters.
