Galloway had 18 points and three assists, Carl Jones had 16 points, Halil Kanacevic had 10 points and 13 rebounds, and Daryus Quarles had a season-high 15 points for the Hawks, who are 18-10 and 8-5 in the conference.
"It is real simple. We don't have a complicated program. We have one rule: Be on time. If you can't get three floors down the hotel for a walk-through, that is where you deserve to start the game," Martelli said of Galloway's coming off the bench after 27 straight starts this year and 33 in a row last season as a freshman.
Galloway entered the game with 15:43 left in the first half. A few minutes later he hit back-to-back three-pointers (his only two treys of the game) and scored eight straight points to ignite a 14-0 run by the Hawks as they took a 22-9 lead.
"We made sure we played defense first," Galloway said of the first-half run.
The Hawks led 37-20 at halftime, but GW (9-17, 4-8), which was without all-league guard Tony Taylor for much of the first half because of foul trouble, cut the lead to 64-60 with 2:13 left on a basket by Nemanja Mikic.
That was as close as GW got, as Jones hit a three-pointer to make it 67-60 and Quarles' free throw made it 68-60 with 1:04 left.
"Carl Jones hit a big three in the corner," Martelli said.
Taylor (team-high 14 points) made it 68-62 with a layup, but C.J. Aiken of the Hawks put the game out of reach with a dunk to make it 71-64 with 27 seconds left.
"We knew they would make a run," Jones said.
The Hawks have won three in a row and five of their last six games.
"We know what is at stake. We feel we can win on the road," Quarles said. "We just wanted to play hard [early on]. We knew what we were going to get when Langston came into the game."
