There are two undefeated teams in Big East play left.
One was predictable. At 5-0 in league play, it's no surprise that a preseason top five team like Villanova would be without a blemish.
The other undefeated team, Pittsburgh, was picked to finish in the bottom half of the league and made few people's preseason NCAA Tournament brackets.
Jamie Dixon has taken a cast of fairly talented, inexperienced players and turned them into a typical Ben Howland Pittsburgh team. For the first time in several years, the Panthers have returned to their roots and become one of the toughest, most physical teams on the defensive end of the floor.
The results of Dixon's team's makeover are shocking. Pittsburgh has won eight in a row, including three consecutive road games against Syracuse, Cincinnati, and Connecticut. In a mere four weeks, Pitt went from not receiving a single vote in the Bleacher Report Top 25 to receiving 299, good enough for a 10th-place ranking.
While Pittsburgh is rising, Purdue is falling, rapidly.
After starting out the season at 14-0 and winning their first two conference games, the Boilermakers lost an acceptable game—at Wisconsin, one of the toughest places to play in America.
What happened next wasn't acceptable. Robbie Hummel scored 28 points in the first half against Ohio State, but Purdue wasted his performance, blowing a double-digit lead late at home.
If two losses weren't enough, Northwestern sent Purdue spiraling one more time, taking the Boilermakers down in Evanston. With another road game against Illinois coming up, Purdue's streak could reach four games.
The Boilermakers still have the résumé of a top 10 to 15 team, and that's where Bleacher Report voters ranked them.
Also, after North Carolina's disastrous week, the Tar Heels barely stayed alive in the poll. With six losses, including three in their last four games, the Tar Heels are falling apart. One more loss to Wake Forest this week and Roy Williams' team could be in trouble come March.
