University of Louisville defensive coordinator Todd Grantham said his side of the ball has improvement to do but noted the Cardinals have had a "very good week" of practice preparing for Samford.
The Cardinals are 0-3 heading into Saturday's 6 p.m. contest at Papa John's Cardinal Stadium.
Grantham talked about what he wants from the defense this week and in the future, while linebacker Keith Kelsey also chatted with the media on Wednesday night after practice.
The second-year defensive coordinator said losing is not fun.
"Our guys competed last week and there was a lot of good things," Grantham said. "But we have to continue to work and we have to realize where we are that it could come down to one play, one possession."
