POSITIVES

—Short pass-rusher with a good first step and natural leverage at 6'1", 317 pounds.

—Natural anchor to play nose tackle despite smaller frame.

—Possessing an excellent work ethic and motor, he gives chase on pursuit plays.

—Knows how to use his hands to free up from blockers and is rarely stopped one-on-one.

—Isn't slippery in gaps but generates pressure up the middle by driving the center off the ball with a bull rush.

NEGATIVES

—Tested below NFL thresholds in the 40 (5.38 seconds), three-cone (8.15 seconds), short shuttle (5.02 seconds) and broad jump (96 inches).

—Likely a two-down player in the NFL, which affects his draft value.

—Scouts told us his poor combine and lack of pass rush could make him a Day 3 player.

—Shorter arms (33 ½") show up on tape as he struggles to split double-teams.

—Needs to learn to drive off the ball better in the run game.

OVERALL

Derrick Nnadi was a fantastic college football player, but he doesn't hit all the marks for tools needed to be an early draft pick. He's likely scheme-specific to a 3-4 team looking to add a nose tackle who can get a little upfield push if kept in on third down.

GRADE: 6.25 (Round 3)
