A long-limbed athlete, Armstrong sticks out on the basketball court and gridiron. As a junior in 2025, he led Lincoln Central with 342 receiving yards and tied for the team-high with 22 catches. A pair of touchdown receptions were the second most on the squad. Armstrong also racked up 40.0 tackles, 29 of which were solo stops. He recorded 1.5 tackles for loss as well. Evidence of how Armstrong achieves success on the field can be found in his 11th-grade highlight video. The first clip has him reading and reacting at free safety before dropping a receiver in his tracks. On the second cut, Armstrong lines up on the outside and hauls in a touchdown over the top of two defenders at the goal line. A projectable frame and athleticism give him a sizable ceiling and make Armstrong one to watch this coming fall.
