Has a good motor and works hard in pursuit, but lacks the closing range to make plays on the ball carrier from the backside. Plays way too high in the run game and consistently allows offensive linemen to get under his pads and is easily washed away from the football.
Impression: A lacking athlete who doesn't possess the physical skill set to play at the next level."
Positive: Somewhat athletic player who's shown the ability to make plays up the field. Displays good movement skills, fluid changing direction and easily gets down the line. Rarely off his feet, works hard, and nicely redirects to ball carriers. Fluid if asked to twist or stunt. Plays smart football and gets his hands up to bat away the throw if he cannot get to the passer.
Negative: Possesses marginal speed and a minimal burst. Cannot cut off the corners. Lacks strength at the point of attack and easily controlled by a single blocker. Displays minimal moves working to come free from blocks.
Analysis: Kooyman showed ability the two seasons he was fully healthy and has the size to stand up over tackle in a 3-4 alignment at the next level."
