Lamar Jackson is the runaway leader for the Heisman Trophy, but his Louisville Cardinals will need plenty of help if he is to play for even bigger hardware.

The Cardinals are fifth in the rankings -- up one spot from last week -- behind No. 1 Alabama, No. 2 Ohio State, No. 3 Michigan and No. 4 Clemson.

For now, Jackson will have to hope for some help, and keep shaking his head.
