If you're looking ahead to the NFL draft and those all important rookie cards, it should prove to be an interesting season. The impressive showings of quarterbacks, particularly Tim Couch of Kentucky and Dante Culpepper of Central Florida, at last week's NFL combine testing in Indianapolis has scouts saying that Heisman Trophy winner Ricky Williams of Texas might slip in next month's NFL draft. While Williams may wind up having the superior overall career in the NFL, teams like expansion Cleveland, Philadelphia and others with selections in the first half dozen or so picks believe a top young quarterback is a more pressing need for their teams.
