CLEMSON, S.C.— Clemson's got much more than just a stellar offense — and proved that against Louisville on Saturday. The Tigers (4-2, 3-1 Atlantic Coast Conference) came into this one leading the ACC in total yards and points per game, yet defeated the Cardinals 23-17 without scoring an offensive touchdown. "That's crazy," said Clemson receiver Adam Humphries, who started things off with a 72-yard punt return TD, the Tigers first such score in five years.
