The Jacksonville Jaguars faced the Miami Dolphins in the preseason finale. The bout gave several players one last opportunity to make an impression and either secure a roster spot or move up on the depth chart. A rookie linebacker most definitely took advantage of his chances.
2025 fourth-round pick Jack Kiser was never in danger of getting cut, but that didn't stop him from coming through in Week 3 of the preseason, logging four total tackles and one sack. Couple that with a strong training camp, and it's fair to say that the former Notre Dame Irish was among the biggest Jaguars winners of the preseason.
