Gene Riordan

Physical Profile

Listed at 6-4, 275 lbs. Taller than 36% and heavier than 11% of 2026 Interior Offensive Line prospects in the SEC Scouts database (207 with a listed size).

Play Style

This is an inference from his profile, not from film: Riordan projects as an effort-driven, physical interior blocker whose defensive-line background shows in how he plays. Expect a lineman who finishes blocks and can move defenders on combination blocks, but whose pass-protection technique is still developing. That matches both his own goals and his rating, a high-floor 4-star rather than an early-impact one. His size and two-way athleticism are typical of the zone-scheme guards Iowa has turned into starters.

Strengths

• Recruiting market backs up the rating: he had 20-plus offers, including Oklahoma, Penn State, Auburn, Illinois and Minnesota. Several of those staffs recruit linemen seriously, so the IOL ranking is not propped up by a thin offer list.
• Clear physical growth: from 6-4/250 as a sophomore to 6-5/280-302 by college, while still carrying enough athleticism to play defensive line in high school.
• Mindset suited to interior line play: he describes himself as competitive and coachable and said linemen 'can't take any plays off.' He was named all-conference and all-area in 2024 for a strong Hinsdale Central (IHSA 8A) program.
• Two-way experience: playing defensive line gives him a feel for leverage, hand fighting and how defensive fronts move, which carries over to pass protection and combination blocks in the run game.

Areas to Improve

• Pass-protection footwork: he named it himself as a sophomore offseason goal. Against Big Ten interior rushers he needs a consistent set, a firm anchor against power, and hand placement that holds up against quick counter moves.
• Adding weight while keeping movement: going from 250 to over 300 lb in about two years means his body is still settling. He needs to keep his lateral quickness and ability to get to the second level for Iowa's outside-zone run game.
• Moving to guard from a high-school role that included tackle and defensive line: he has to learn to play in tight spaces against defenders who line up directly over him, and handle combination blocks and twist/stunt pickups at college speed.

College Projection

He is on Iowa's 2026 roster as a freshman, #78, and is likely to redshirt. Iowa usually gives young linemen a year or two in the strength program, and he arrived in a five-lineman recruiting class that makes competition for the two-deep crowded. The realistic timeline is a rotational or depth role in 2027, a push for a starting guard spot in 2028, and a chance to become a multi-year starter from 2028 to 2030. His ability to play center could speed that up if the depth chart opens there.

NFL Outlook

He is a Day 3 draft prospect with a path to Day 2 if the added weight stays functional and his pass protection becomes reliable. Iowa's record of producing NFL interior linemen helps his odds. Most likely outcome: a three- or four-year Big Ten starter drafted in the middle rounds or signed as an undrafted free agent, with his draft stock decided mostly by his anchor and length measurements at the combine.

Best Fit

A patient program with a strong line-development track record that runs a zone-heavy scheme, where his mobility and effort on combination blocks matter more than a first-year contribution. Iowa is close to ideal: Kirk Ferentz's staff develops linemen over several years, the strength program can manage his weight growth, and the Hawkeyes' outside-zone and duo run game suits a physical, athletic guard.
