Men's Power Rankings: The race for the fourth 1-seed is on - ESPN

After a short stretch that featured fewer top-10 upsets than we've become used to seeing this season, this past week upended the 1-seed discussion and left plenty at stake entering the week before Selection Sunday.

Tennessee had the inside track for the final 1-seed at the start of the week, but the Volunteers saw their seven-game winning streak snapped on their home floor against Kentucky on Saturday. Arizona then assumed pole position — but that was before the Wildcats suffered a surprising 13-point loss at USC late Saturday night. Earlier in the day, a potential sleeper for the final 1-seed, Iowa State, saw its hopes evaporate with a loss at Kansas State.

The one winner from all the chaos? North Carolina, which went into Duke and knocked off the Blue Devils, clinching the Tar Heels' first outright ACC regular-season title since 2017.

Arizona's loss likely takes it out of the mix, leaving a battle between Tennessee and North Carolina for the final spot. The Tar Heels hold the head-to-head edge, beating the Volunteers in Chapel Hill back in November. Tennessee has the slight metrics edge, especially from a predictive perspective. The Vols' best wins have come against Kentucky, Auburn, Alabama (twice) and Illinois, while Carolina has two wins over Duke and the win over the Vols.

Will either team win its conference tournament? That could be the deciding factor.
