Louisville players have frequently talked about measuring up Saturday against North Carolina, figuratively and literally. The Tar Heels are big and long.
They are the biggest opponent the 19th-ranked Cardinals have faced this season. The shortest player on the Tar Heels' offensive lineman stands 6-foot-4 and features a trio of 6-7 blockers. North Carolina's receivers also have a distinct height advantage over Louisville's starting secondary.
Then there's North Carolina's defense, anchored by 6-3 tackle Sylvester Williams, who passed on entering last spring's NFL draft to return for his senior season.
