FAIRFAX, Va. -- Marc Sonnen connected on seven 3-pointers and had 21 points to lead Northern Iowa to an 82-77 overtime victory over George Mason, snapping Patriots' 14-game home winning streak.
Tuttle finished with 18 points, going 12-for-14 from the foul line.
George Mason (6-4) got 20 points from Sherrod Wright, but was undone by some costly miscues and inconsistent play from point guards Bryon Allen and Corey Edwards. They combined for 21 points but also had eight turnovers between them.
George Mason trailed 80-77 before Allen committed a turnover with three seconds remaining in overtime. The Patriots' Johnny Williams was forced to immediately foul Tuttle, who hit his final two free throws to provide the final margin.
Former Kentucky guard Ed Davender, the only Wildcat with at least 1,500 points and 400 assists, has died. He was 49.
Guard Naz Mitrou-Long, whose 2015-16 season ended in December due to hip problems, has been granted a hardship waiver for the coming season, Iowa State said.
As the Sooners look to life without superstar Buddy Hield and his sidekicks, it's clear their unseasoned players will need to grow up fast.
