NFL Combine: Johnny Manziel runs 4.56 40, Teddy Bridgewater opts out

Johnny Manziel ran an impressive 4.56 at the NFL Combine Sunday. Manziel's sprint was fast enough for NFL Network analysts to draw comparisons to Colin Kaepernick's Combine performance.

"Manziel finished the 40 fast" usually means something else.

Johnny Manziel ran the 40. Media selfishly disappointed he didn't chug it.

Central Florida quarterback Blake Bortles, also considered a first-round quarterback by many draft experts, ran a 4.81 second 40 Sunday morning. Louisville's Teddy Bridgewater opted not to run or participate in any other drills Sunday.

Bridgewater, like Seinfeld, refuses to run

Manziel wasn't the only quarterback to impress in the 40-yard dash. Fresno State's Derek Carr, known primarily as a pocket passer, ran a 4.65-second 40. Northern Illinois quarterback Jordan Lynch ran a 4.72-second 40, while Clemson's Tajh Boyd covered the distance in 4.75 seconds. Alabama's A.J. McCarron ran a Tom Brady-like 4.91.

Love the NFL combine tradition of gushing over QB 40 times and then criticizing them for running too much when they get to the league.

South Carolina's Connor Shaw posted the day's top time with a 4.55-second sprint. Virginia Tech's Logan Thomas and Miami's Stephen Morris both posted 4.57-second 40 yard dashes.

Many of the pocket passers declined to run Sunday, including LSU's Zach Mettenberger. Georgia quarterback Aaron Murray, who is recovering from a torn ACL suffered in November, also did not participate.
