TRENDS TO WATCH

Trending up: Top-10 upsets. Five top-10 teams in the Associated Press poll suffered upset losses last week, including three to unranked opponents.

Trending down: Marquette dropped its third straight game Wednesday vs. Seton Hall. The Golden Eagles not only have blown their chance to win the Big East outright, but they gave Villanova a chance to achieve that feat.
