Here's an updated look at the top-25 power rankings, including some movement up and down after some offseason updates. Duke Blue DevilsDuke isn’t likely to add to its already stacked roster for next season, having already done its work early on. For a team that already had some of the best frontcourt depth, Spears only makes them better if he can have a significant impact. Guards Christian Harmon and Jurian Dixon add to the perimeter depth, while the frontcourt depth is up there among the best. Alabama could also continue building its frontcourt depth after last year’s issues to ensure it’s not a weak spot.
