No. 1 Auburn has been unscathed while running the gauntlet in the loaded Southeastern Conference, where nine teams currently are ranked — including four of the top six.On top of that, five others in the 16-team league have been ranked at some point this season.But somehow Auburn (21-1, 9-0) still has a clean SEC slate. The Tigers’ 15-game league winning streak dates to last season and includes three wins in the conference tournament.Auburn will face another SEC challenge on Saturday afternoon when it hosts No. 6 Florida (19-3, 6-3).The Gators know the drill. A month ago, they toppled another top-ranked SEC team, stunning then-undefeated Tennessee 73-43.As Florida prepares for this matchup with Auburn, which has won 14 games in a row overall this season, the status of perhaps its most vital player is uncertain.Walter Clayton Jr., who averages team highs in points (17.4) and assists (3.8), sat out the Gators’ 86-75 win Tuesday over Vanderbilt with an ankle injury.”Obviously, we would always prefer him out there,” Florida coach Todd Golden said. “But we have a lot of season left.”The value of the team’s point guard was demonstrated last Saturday when Florida lost its rematch with Tennessee, 64-44.With Clayton scoring 10 points in the first 14 minutes, he helped put Florida up 15-14. But after Clayton rolled his ankle and was limited the rest of the way, the Volunteers outscored the Gators 50-29.In Florida’s victory over Vanderbilt, Denzel Aberdeen replaced Clayton, providing 13 points, three assists and no turnovers, doing “an incredible job controlling the game,” Golden said.Will Richard bounced back from a season-low two-point performance against Tennessee, in which he took just two shots, to record 21 points on 8-of-11 shooting from the field vs. Vanderbilt.
