On offense, Andrew Luck, Robert Griffin III and Trent Richardson are among the most athletic members of the 2012 NFL draft class.
On defense, there are a multitude of physical freaks who are deceptively strong, speedy and agile.
Let's take a look at the most athletically gifted defensive prospects who'll almost assuredly be selected in the first round.
Michael Brockers, DL, LSU
As a 21-year-old sophomore, Brockers was a surprise entry to this year's draft, but he's easily one of the most athletic defensive linemen in the class.
At 6'6'' and 305 pounds, he possesses the strength to bull-rush his way to the quarterback and aggressively reaches the backfield with shocking speed. He also has a variety of moves in his arsenal and doesn't take plays off.
And 6'6'', 305-pound mammoths shouldn't be able to move as fluidly as Brockers does.
He has eye-opening leaping ability as was evidenced on his field goal block against Alabama in the national championship game.
With room to add more bulk to his frame, Brockers has the potential to be a disruptive, pass-rushing defensive tackle at the next level and could even line up as a defensive end.
Nick Perry, OLB/DE, USC
At 6'3'' and 250 pounds, Perry is an elite athlete. Not surprising for a guy from USC, right?
He's tremendously agile and smooth when getting to the passer and often beats opposing tackles with speed rushes to the outside.
Perry doesn't have a variety of counter-moves, but he can get to the quarterback with his quickness and footwork alone.
I wouldn't call this 21-year-old junior the strongest hybrid prospect ever, but he can surprise offensive linemen with an occasional powerful bull-rush.
He's can be a good run defender due to his phenomenal burst and speed and is strong enough to get off blocks.
A special, more underrated player.
Vontaze Burfict, LB, Arizona State
Burfict has an NFL-ready body at 6'3'' and 250 pounds and is the most ferocious sideline-to-sideline, hard-hitting linebacker in the 2012 class.
Sometimes this Arizona State product overruns plays, because he's so quick to the football.
Burfict carries his weight well, and although he isn't great in coverage, he's Patrick Willis-like making plays within the first five yards of the line of scrimmage.
He's got great body control and can slip or shred blocks to take down the ball carrier, or slip into the backfield.
It'll be interesting to see his 40-yard dash time, because he plays extremely fast on the field.
