Despite forcing an NCAA-record 10 fumbles and leading the nation in sacks with 20 as a senior at Louisville, Dumervil dropped to the fourth round in 2006 due to his size. It was the rest of the league's loss, as he had 8 1/2 sacks as a rookie; in three games this year he already has four sacks and an interception.

Like Dumervil, Ryans slipped in the 2006 draft because of his lack of bulk. Houston took him in the second round, and the move paid off as Ryans went on to lead the NFL in solo tackles, with 126, and earn defensive rookie of the year honors. This season he's the captain of a much improved Texans defense.
