5. Khalil Mack - Outside Linebacker - Buffalo

Mack has been at or near the top-15 on just about every draft board since the end of the college football season, and now he's solidly in the top 5.

He's the type of ultra productive playmaker who, even while playing for a small school, held up well against elite competition. Just ask Ohio State.

With a 4.65 40-yard dash and elite performances in the vertical jump and broad jump, he's got the explosiveness to be an impact performer from day one, and looking at his tape from Buffalo, its easy to see why he's projected to go so high.

Expect his versatility and playmaking ability to land him a starter role this season, and to be in contention for the Defensive Rookie of the Year.
