It was a bad night for men's college teams ranked in the Top 15.
No. 6 Virginia, No. 9 Syracuse, No. 10 Tennessee and No. 14 Iowa were all upset Wednesday night, with No. 3 Duke the only Top 15 team to escape with a victory.
The surprise wins had the teams feeling good, but they tried to maintain perspective.
"We're not going to get overexcited," Boston College coach Al Skinner said calmly after the 17th-ranked Eagles' 65-63 victory over Syracuse. "They were happy, but it's not like we won the Big East title or anything like that."

"We know everyone isn't going to like us. When things go bad, people tend to jump ship and go sour," said the Wolfpack's Damien Wilkins, who scored 21 points. "But we've just kept our composure all year long."
Joe Johnson scored off a rebound while two Tennessee players stood and watched, apparently thinking the ball was out of play, as Arkansas beat the Volunteers 82-77 in overtime.
