In front of the Wildcats' team, Collins announced Montgomery would receive a full scholarship this year.
"He has as much energy as anybody on the team. ... He's our best perimeter defender," Collins told the team in a clip posted on Northwestern's You Tube channel. "The guy through 12 practices that has done the best job of doing what he's supposed to do every day is James."
The video clip also shows Montgomery, who is from Los Angeles, sharing the news by phone with his overjoyed mother and sister.
Montgomery spent his freshman season as a practice player with the women's team before making the Wildcats' roster as a sophomore. He scored 17 points in limited action over the last two seasons under coach Bill Carmody and clearly made a quick impression on his new coach, Collins, this season.
