The Bears have won 21 straight games dating to last year’s run to the NCAA championship. The league also has five of the top 12 teams in KenPom’s adjusted defensive efficiency statistics. The league headlines the national AP Top 25 schedule with three games featuring two ranked teams. The Southeastern Conference also has two of those games. Unranked teams to watch this week include Oklahoma, Loyola Chicago and Miami.
