Mulder made plenty of noise as an Aplington-Parkersburg junior in 2025. He produced 32.5 tackles, 22 of which were of the solo variety. Mulder piled up 9.0 tackles for loss and a pair of sacks. His 11th-grade highlight video reveals a disruptive middle linebacker who does well in diagnosing the opponent’s intentions before the snap. It helps him get downhill in a hurry against the run. Mulder shoots the gaps and arrives with impact, wrapping up and dropping the ball carrier. He can power through blocks or disengage from them quickly with strength and active hands. There’s straight-line speed and lateral quickness present. Fluid movements and easy change-of-direction aids in pass coverage. Mulder would be a special teams’ asset on the next level as well.
