That challenge begins Saturday when they host Missouri (11-2) in the conference opener for both teams.Auburn’s only loss this season came at then-No. 9 Duke, 84-78, on Dec. 4.”It was the toughest nonconference schedule in the history of Auburn basketball,” coach Bruce Pearl said. “So, I’m very, very proud of our kids. A lot of the games we played were on neutral sites and away from home, so we demonstrated that we can win away from Neville (Arena).”Auburn defeated Monmouth 87-58 at home on Dec. 30 in its final tune-up game.”Now, we get ready to start the toughest conference schedule in the history of college basketball,” Pearl said. “Like, there’s maybe never been a league like this, and it’s going to be — the strong are literally going to be the only ones who survive. Hungry, healthy, humble is the way to get through it.”Matchups are going to matter. We’re going to lose games. But we can’t let a loss affect us the next time out. We’ve got to be beat instead of beating ourselves. But we’re healthy and we’re ready.”Auburn forward Johni Broome has been a matchup problem for every opponent.
