Detroit Lions general manager Martin Mayhew recently said he expects his high draft 2013 NFL picks to have an immediate impact this season.

Lions rookie defensive end Ezekiel Ansah had only 41/2 sacks at BYU last year, but will be given every opportunity to start as a rookie. If history is any indication, Ansah will not turn into the second coming of Reggie White during his first NFL season.

Over the past six seasons, 28 defensive ends have been first-round selections in the NFL draft. Washington Redskins standout Brian Orakpo is the only player from that group to record double-digit sacks in his first NFL season. Five players failed to record a sack as a rookie, and two players were out of the NFL after only four seasons.

Here is a look at how first-round defensive ends have fared recently in the NFL:
