It was a weird Saturday in the Big East.

The league's three schools that are ranked in the current Associated Press poll -- Villanova, Seton Hall and Butler -- each lost at home to schools unranked in the current Associated Press poll, which represents the first time in history that's ever happened on the same day. Villanova was a 5.5-point favorite over Creighton -- but lost 76-61 inside Wells Fargo Center. Seton Hall was an 8.5-point favorite over Xavier -- but lost 74-62 inside the Prudential Center. And Butler was a 6.5-point favorite over Providence -- but lost 65-61 inside Hinkle Fieldhouse.

Like I said, weird stuff.

The result is an obvious shakeup in Sunday morning's updated CBS Sports Top 25 and 1 daily college basketball rankings -- where Villanova is now the only Big East school still in the top 10. The Wildcats' drop from No. 5 to No. 8 allowed Louisville, which won 77-57 at NC State on Saturday, to move into the top five. And, yes, Gonzaga remains No. 1 thanks to a 15-game winning streak featuring 11 double-digit victories. The Zags' next game is Thursday against Loyola Marymount.
