Porter’s Scouting Report
A two-way player out of Bettendorf High School, Porter is a Bettendorf, Iowa native who played both wide receiver and cornerback. He was also a track athlete, breaking the Class 4A state record in the 400-meter dash.
Porter committed to play college football at Iowa State as a three-star recruit at wide receiver. As a true freshman in 2019, he played in three games as a wide receiver but ended up redshirting. That year gave him an added year of collegiate eligibility, as did the 2020 COVID-19 season.
Porter finished his redshirt freshman year with five tackles on special teams, catching one pass for no yards. In 2021, he stepped into another special teams role, taking 245 reps on special-teams units and playing in all 13 games. He took just 15 offensive snaps all year, not generating any targets in the passing game.
Having gone three seasons with just one catch, Porter made the switch over to cornerback leading up to the 2022 season. He factored into Iowa State’s defensive back rotation, playing 153 total defensive snaps and ending the year with 15 tackles and a pass deflection.

Though only a rotational defender in 2022, Porter was a standout on special teams. He used his size and length to his advantage, blocking a punt against Kansas State.
In his fifth collegiate season in 2023, Porter settled into a similar depth role for the Cyclones. He blocked another punt on special teams, with five of his 10 tackles coming in that area, yet his allowed passer rating went from 139.6 in 2022 to 75.7 in 2023.
The 2024 season was Porter’s sixth collegiate season, and it marked his first opportunity to crack Iowa State’s starting lineup. And he took advantage of the long-awaited chance, finishing the year with three interceptions.
Porter dominated in coverage, allowing a completion percentage of just 29.4% and a passer rating of 4.7 when targeted. He was a shutdown defender in coverage, allowing just five receptions on 17 targets in 12 games.
Strengths
- Physical specimen with elite height and length for the cornerback position.
- Long arms give him a better catch radius than the average cornerback, and he’s an explosive jumper who attacks the 50/50 ball well.
- Ran a 4.30 in the 40-yard dash at the Combine, and that blazing speed shows up on tape.
- Experience at wide receiver shows up in how he tracks down the deep ball, as he high points the jump ball well and has tremendous body control attacking in the air.
- Proven special teams contributor who uses his long arms and elite speed to block punts.
- Stellar gunner on special teams.
- Accelerates well upfield coming out of his breaks with elite deep speed, allowing him to defend vertical route concepts well.
- For an inexperienced cornerback, he shows pretty good processing ability in off-man and zone coverage.
- Maintains good patience letting route concepts develop when he’s covering off the ball.
- Has good downhill quickness coming out of his backpedal, demonstrating ideal longitudinal agility.
Weaknesses
- One-year starting cornerback who didn’t crack the starting lineup until his sixth year in college.
- Doesn’t have nearly as large of a sample size to work off of as most other top cornerbacks in the 2025 NFL Draft class.
- For a bigger cornerback, his physicality and hand usage through a receiver’s stems isn’t as great as one would hope.
- Struggles with taking blocks head-on, playing a part in his issues against screens that come over his way.
- Has a high center of gravity as a tackler, and he wraps up too often leading with his arms.
- Physicality at the catch point is rather pedestrian.
- Processing speed in man coverage isn’t all that great, as he can be a split second too late to diagnose route concepts and read the movements of opposing receivers.
Current Draft Projection and Summary
Porter is as boom-or-bust of a CB prospect as you can get in 2025. By drafting him, you’re getting a moldable ball of clay with elite height, length, and speed. He has top-notch ball skills, with his background as a receiver showing up in his coordination and ball-tracking capabilities.
Porter’s elite physical attributes see him fare well in coverage, but he’s shown some intriguing chops in coverage unbefitting of a first-year starting cornerback. His ability to process off the line of scrimmage in off-man and zone are very encouraging.

The concerns on tape are about what you could expect given Porter’s profile. He’s lanky and lacks tremendous physicality, and he’s a raw processor who gets caught diagnosing plays a split second too late too often.
Given his relative inexperience and raw skill set for his older age, it feels like a stretch to warrant taking Porter in Round 1. Early in the second round might also be a bit steep, but his physical upside is too strong to ignore. Though he could make his way into Round 2 due to his tools, early in the third round feels like good value for Porter.
