Landri is a very good interior pass rusher, with a great first step, and is strong enough to work past blockers. He has great lateral quickness, which allows him to work down the line of scrimmage to make tackles in the run game. Very fundamentally sound athlete with good technique, both in tackling and pass rushing.
NEGATIVES
He's grossly undersized, and will have to move to the outside in the NFL. He gets overpowered on the interior at times, and has trouble shedding blockers once he's engaged. Since he's not an elite athlete, he'll need to get bigger and stronger to be a viable draft prospect. He lacks closing speed, and loses sacks to more athletic quarterbacks.
FINAL WORD
Landri is an interesting prospect, because he's such a small interior player, but he works very hard to make plays, and does well for the most part. As I said, he'll never play DT in the NFL, unless he finds a way to add 30 lbs. this year, but could work out well as a 4-3 DE with his combination of pass rushing and run stopping skills.
