The University of Louisville men's basketball team is back in action Saturday, taking on top-ranked Pittsburgh.U of L Coach Rick Pitino says the Panthers' number one ranking has no effect on his team's preparation for the game."We know that if Pitt was number 30 we know we'd have a tough ballgame....we know we're going to have a difficult game. The rankings are meaningless to us." Pitino said Friday.The Cards are ranked 20th in the country.
