POSITIVES

– Solid instincts as a run defender to key and diagnose plays and beat offensive linemen to the spot.

– Takes on blocks with his hands and has decent upper-body strength to get extension.

– Works his hands well to escape blocks.

– Sure tackler who wraps up and rarely misses.

– Physical and uses his hands well in coverage to help disrupt routes against tight ends.

– Good pass-rusher when blitzing. Shows a rip move, cross-chop and shoulder dip that he can win with. Also has the strength to run through/bull-rush running backs.

---

NEGATIVES

– Older prospect. Will be a 25-year-old rookie.

– Average-at-best athlete who will likely struggle to cover shifty running backs and athletic tight ends in the NFL. Also lacks the agility to avoid getting picked against rub routes.

– Questionable awareness in coverage. Has a habit of driving out of his area in zone coverage and being late to pick up his man in the flat in man coverage.

– Subpar lower-body strength leads to him getting pushed out of his gap against offensive linemen when he doesn't land his hands first. Tends to give up extra yards after contact versus physical running backs as well.

OVERALL

After spending six years at Notre Dame, Jack Kiser is one of the oldest prospects in the 2025 NFL draft class. He'll turn 25 at the beginning of his rookie season.

That could cap his ceiling for some clubs, but he can be a solid run-defending linebacker and special teams contributor in the NFL.

Kiser's instincts against the run stand out, as he's quick to key and diagnose plays to beat offensive linemen to the spot, especially against gap runs. He also uses his hands to take on blocks, which helps him disengage against offensive linemen and make tackles. He uses good technique to consistently bring down running backs and rarely misses.

However, the former Golden Domer is limited athletically and will likely struggle in coverage in the NFL. While he has the upper-body strength to disrupt routes, tight ends and running backs who can fight through contact will be able to create separation against him. Notre Dame would often take him out in passing situations in favor of better coverage 'backers.

Kiser can impact the passing game with his skills as a blitzer, though. He's shown a handful of pass-rush moves that he can beat running backs with, including a rip, shoulder-dip cross chop and bull rush to get pressure on the quarterback. He's also decent at spying and closing on the quarterback.

Overall, Kiser has potential as a two-down linebacker in the NFL. He was also the Fighting Irish's 2023 Special Teams Player of the Year, which will help him add value to an NFL roster. However, his age and lack of athleticism could limit his growth and hurt his draft stock.
