Like them or not, one thing about Louisville teams in all sports over the years is they want to win and think they can win, even though they are underdogs in many cases.
It all goes back to being classified as a second class citizen to Kentucky for many years. When they get the chance they play with a chip on their shoulder, like old ND FB teams used to.
A couple of years ago the ND women's golf team gave UofL a thrashing on the Cardinal Club course. I was out there both days and after the tourney ended I was having a drink with the guy who owns the course. He said he didn't care how many shots ND beat them by, the Cards were still better player for player. They live with that outlook.
