George Washington's deliberate play shortened the game and helped disallow South from scoring between the 2:29 mark of regulation and at the 2-second mark of overtime on a layup by Cody Monroe.
South had the ball for the final possession of regulation, but a Cox baseline runner was off the mark with 2 seconds left.
"We're weren't trying to hold it, we just couldn't get around their defense," Greene said. "They're as good a halfcourt trapping defense as there is in the state. We were trying to get it reversed, be patient and find a seam.
"We didn't want to run up and down with them and I think the guys did a great job."
In overtime, Dominik King scored a basket off an Eddy assist to give GW the lead and Kay had four foul shots in the final 22.8 seconds to close it out.
Wes Mitchem led South with 17 points, 10 of which came in the fourth quarter. George Washington tried to match up with South's size advantage with reserve Cai Corena, who had only four points but grabbed seven rebounds in the second and third quarters.
In the end, however, it was Breeden leading Eddy's support case for the win.
"We have to have somebody else besides Luke make plays late," Greene said. "I've done this decades and I've coached some great people. I've never coached a better person than Austin Breeden. I'm really happy, I could get emotional."
