Georgetown’s Markel Starks lost the handle driving into the lane and Spencer connected on 1 of 2 from the line. He then punctuated the win with a steal and dunk.
Georgetown led 36-25 at the half.
The Hoyas started fast, scoring the first nine points of the game. It could have been more, but they struggled from the line, connecting on 9 of 16 attempts in the opening 20 minutes.
Northeastern committed nine turnovers, but got a solid half inside from David Walker, who had six points.
Northeastern entered the game known for its 3-point shooting, but won without attempting a shot from beyond the arc in the second half.
The Hoyas were 0 for 8 from 3 in the final 20 minutes and 3 for 16 for the game.
“I think we took too many 3s at the wrong time today,” Thompson said. “We didn’t execute what we were trying to execute. We didn’t execute inside and outside, we didn’t get the ball to the corners enough.”
Hoyas forward Nate Lubick said they were beaten by a better team and echoed Thompson’s call for he and his teammates to do some soul-searching.
“I give them all the credit the world,” he said. “We executed relatively well in the first half, and we did not do anything we needed to do in the second half to continue our execution and do what we need to do to win games.”
