While No. 2 Louisville hasn't played the toughest schedule so far, it certainly has looked the part of a national championship contender, particularly when it comes to offensive efficiency.

The Cardinals enter their Wednesday night nonconference home game against South Carolina Upstate canning an NCAA-best 56.6 percent from the field, along with 44.3 percent from the 3-point arc and 74.3 percent at the foul line. They are averaging 85.8 points per game and drawing assists on just over 56 percent of their field goals.

But coach Chris Mack knows they won't keep making nearly 57 percent of their shots once they start playing Atlantic Coast Conference games, so his point of emphasis during practice is on things that can help them win when the ball won't drop.
