The Broncos have engaged in discussions regarding a draft trade for USC quarterback Mark Sanchez, according to an NFL source. In possession of the No. 12 and No. 18 overall picks in the NFL draft, which begins Saturday, the Broncos understand they may have to move up to snag Sanchez, who is drawing interest from several teams. One possible trade partner is the Jacksonville Jaguars, who want to drop down from No. 8 overall.
