Tests keep coming for Auburn and Duke, who collide at Cameron Indoor Stadium in a typical prove-it game in a rare environment on Wednesday night.No. 2 Auburn and No. 9 Duke square off less than one month into the season as two of the most battle-tested teams in basketball. They’re matched as one of the marquee games in the crossover showcase known as the ACC-SEC Challenge.Auburn (7-0) jumped two spots in the latest Top 25 poll propelled by its Maui Invitational championship. In one of Feast Week’s toughest brackets, the Tigers rallied from 18 points down to beat then-No. 4 Iowa State, handled then-No. 12 North Carolina 85-72 and rolled past Memphis 90-76 in the title game.With a week off to shed any remnants of jet lag returning from the islands, Auburn head coach Bruce Pearl is pointing to another potential resume-building win.”The confidence that we’re going to get from (Maui) is that we know we can play with anybody,” Pearl said. “I promise you this, we’ll stay humble and hungry. We will not begin to think too much of ourselves.”Helping lead Auburn in Maui was fifth-year power forward Johni Broome. The tournament’s MVP, Broome averaged 21.7 points, 15 rebounds, 4.3 assists and three blocks in the three-game sweep. Spearheading a veteran Tigers roster, Broome couldn’t care less about individual honors.”I wanted to come to a place where the foundation was already built, and that’s why I came to Auburn,” Broome said. “Winning player of the year doesn’t matter to me. I care about winning games, and making sure I can help my team in any way.”Broome’s 20.7 points and 12.9 rebounds per game lead the Tigers, while Chad Baker-Mazara adds 12.6 ppg and Denver Jones chips in 11.1.Auburn’s next roadblock is earning its first-ever win against Duke. The Tigers are 0-3 all-time against the Blue Devils, including a six-point loss in the 2018 Maui Invitational.Duke (5-2) has already been through three games against ranked opponents. The Blue Devils had a 77-72 loss against then-No. 19 Kentucky, a 14-point win at then-No. 17 Arizona and a 75-72 defeat against No. 1 Kansas last week in Las Vegas.
