Tebow leads quarterback storylines

This is a unique year at the combine because for one reason or another most of the top-tier quarterback prospects are not expected to throw and/or take part in other drills.

Oklahoma's Sam Bradford is still recovering from shoulder surgery but is expected to throw for scouts in late March, and Notre Dame's Jimmy Clausen is rehabbing after toe surgery and won't work out for scouts until early April. Texas' Colt McCoy has worked toward throwing at the combine, but there has been no indication about his readiness; his status remains up in the air.
