As far as I can tell via Google search, Riordan is an uncommitted senior. That’s a bit surprising after watching him operate against Saint Ansgar during the state semifinals at the UNI-Dome. I could see him helping a number of college programs on either side of the ball. He also has plenty of room for development to determine a position down the road. Riordan moves well and displays smooth footwork as a blocker. On the other side of the trench, he competes with good pad level and uses his hands effectively. In this game, he came up with 8.0 tackles, four of which were solo. He also did his job in the O-Line.

The Warriors reached the postseason in 2024 with Riordan contributing on both sides of the ball. Defensively, seven of his 8.0 tackles were solo. He can eat up space and move on the that front. Riordan stands out even more for his work on the O-Line, which we witness when watching his junior highlight video. He physically overwhelms many of his opponents, getting them on their heels right away before putting them down. Riordan dominates in the run game and has the tools to succeed in pass-pro with more seasoning. He best fits at guard on the next level.
