ACC, Ivy League are week's biggest movers

The ACC returned to the top five while the Ivy League was the biggest mover in ESPN Stats and Info’s weekly college basketball rankings.

The MWC was number five in our previous rankings but the ACC has bumped them out of the top five this week, largely because of a boost in the conference’s human bonus. The computer ranking for the ACC has been steady over the past few weeks, but its human bonus has increased from 12.2 percent to 14.7 percent.

The ACC now has the second-highest human bonus (Big 12 is first with 19.4 percent) and it's been the performance of two teams located outside the state of North Carolina that has helped the conference. While Duke and UNC get the most attention, Florida State and Virginia are a combined 8-2 in their past 10 games and the Seminoles have won seven in a row.

Duke dropped four spots in Monday’s ESPN/USA Today Coaches poll but Florida State and Virginia are in the top 20 in both polls.

While the ACC is improving, the Big East’s rating has steadily declined throughout the season. The Big East is the only conference in the top five with a human bonus under 10 percent and the conference has just four teams in the top 25 and one in the top 10.

The Ivy League improved three spots this week, from 16 to 13, mostly because of Harvard’s success. The Crimson are ranked in both polls for the first time since the week of January 2, and are ranked 21st in the ESPN/USA Today Coaches poll, tying their highest ranking this season.

Murray State is ranked in the top 10 of both polls for the second consecutive week, but the Ohio Valley Conference moved up just one spot to 21 in our conference power rankings.
