ORLANDO — Despite an abysmal overall record, USF arrived at the American Athletic Conference tournament resembling a team on fire more than one on fumes. Problem was, the Bulls encountered a Memphis club fuming mad.Exactly a week after embarrassing the Tigers by 24 points on the road, the Bulls (10-22) couldn’t replicate the romp Thursday at Amway Center. Down by as many as 15 in the second half, they rallied before falling 79-77 in a nationally televised showcase for freshman David Collins (career-best 30 points)."It’s tough," said first-year coach Brian Gregory, whose Bulls were seeking the program’s first three-game win streak in conference play since 2012. "It’s a bitter pill to swallow when you’re playing pretty good basketball and you want to continue to play, and it ends."Down 79-76, the No. 12 seed Bulls had chance to tie after Memphis’ Malik Rhodes missed two free throws with 18.3 seconds left. Point guard Stephan Jiggetts (16 points) got an open look from the left wing but missed. Justin Brown, fouled with less than a second to play, hit the first of two free throws."I actually thought it was going down," Jiggetts said.It was one of the few shots that didn’t fall in the first-round matchup before an announced crowd of 7,856.
