Nebraska CB Alfonzo Dennard's 40-yard dash time (4.55 seconds) at the NFL combine will keep the Lions interested despite his 5-10 height. Dennard's 37-inch vertical jump proves he has the leaping ability to counteract any height disadvantage he may face against tall NFL receivers. He didn't participate in the combine's agility drills, but his closing speed at Nebraska showed he's capable of making up for occasional missteps.
