First-Half Observations

Marra starts for Knowles. 

Pitino went with sophomore Mike Marra over senior Preston Knowles. It's worked. Marra has 7 points, 3 rebounds and 4 assists with no turnovers in 16 minutes.

Who is going to step up with Mack?

Shelvin Mack has 17 of Butler's 23 halftime points. The other scorers are Howard (2), Hahn (2) and Smith (2).

Defending the 3-point line

Butler is 2-12 from three point range.

Louisville is 5-17 for +9 from beyond the arc.

More startling than Louisville's three point numbers are the quality of some of their looks. Butler's perimeter defense is normally superb but tonight the closeouts are slow and late.

Unchartered Territory

Butler's last loss by 10+ points was at UAB in December of 2009, 67-57.

Butler's last loss by 15+ points was at Milwaukee in March of 2006, 87-71.
