Crossin got his feet wet on the Iowa Falls-Alden varsity as a sophomore in 2025. He posted modest statistics on both sides of the ball, including a completion on his lone throw, while spending the rest of his time developing on the program’s lower level. Crossin posted highlight clips from the season on his Hudl page. They mostly feature him lining up behind center, where he moves well and throws with accuracy on the run. Crossin can stretch the field with a strong arm and does so with touch. A good athlete, he can keep plays alive off of schedule and pick up big yards on the ground. Crossin’s speed and elusiveness running the ball leave open the door to playing other positions on the next level.
