When the North Carolina football team takes the field for Saturday's home game against No. 17 Louisville, it will face a challenge it hasn't come across in four decades.
The Cardinals will arrive in Kenan Stadium led by quarterback Lamar Jackson, who set numerous Atlantic Coast Conference records last season on his way to earning the Heisman Trophy. And as the Tar Heels have learned, a chance to knock off the reigning recipient of college football's most prestigious award doesn't come often.
The last time UNC played a reigning Heisman came 42 years ago, when the 1975 team took on running back Archie Griffin and Ohio State in Columbus, Ohio.
