Sebastian Telfair's little brother used a vicious crossover to hit this game-winner

Idaho State guard Ethan Telfair, the younger brother of New York City high school legend Sebastian Telfair, is in his first season in Division I basketball after a two-year stint in junior college.

The 6-foot point guard is making a name for himself in the Big Sky as one of the conference's leading scorers. On Saturday night, he dropped a career-high 30 points, connecting on a game-winner at the buzzer to lead Idaho State over conference-favorite Weber State for a 69-68 win.

The Coney Island native used a double crossover to the taller defender off his feet and create an opening for his buzzer-beater.

This was Weber State's firs loss in league play. The Bengals, picked to finish last in the Big Sky, are now 3-3.

Telfair is averaging 17.8 points and 5.2 assists per game.
