Iowa State cornerback Darien Porter entered the 2025 NFL Combine as a mid-round prospect, but after a historic athletic performance, he has firmly cemented himself as one of the most intriguing players in this year’s draft class. Standing at nearly 6-foot-3 with 33 1/8-inch arms, Porter possesses the ideal frame for an NFL cornerback. However, it was his combination of elite size, length, and unprecedented athletic testing that sent shockwaves through Indianapolis.
Porter put on a dazzling display during on-field workouts, posting a blistering 4.3-second 40-yard dash, a 36.5-inch vertical jump, and an explosive 10-foot-11-inch broad jump. His athletic profile is nothing short of generational. According to the Relative Athletic Score (RAS), which evaluates athletes based on combine performances dating back to 1987, Porter’s numbers ranked him as the fourth most athletic cornerback in combine history. This is no small feat in a league where raw athleticism at the cornerback position has historically translated to elite success.

His rare blend of speed and length is a trait that immediately jumps off the tape. Porter’s track background is evident in his ability to run stride for stride with receivers on deep routes, showcasing an elite ability to recover if beaten initially. His natural ball-tracking ability, a skill developed from his time as a wide receiver, allows him to time his jumps perfectly when attacking the football at its highest point. Furthermore, his explosiveness extends beyond coverage, as he has five career blocked kicks—proof of how effectively he utilizes his burst and length on special teams.
Porter’s intelligence and processing speed are also key aspects of his game. He thrives in zone coverage, particularly in Cover 3 schemes, where he expertly leverages the sideline as an extra defender. Despite his towering frame, he maintains a low pad level, making his transitions in coverage far smoother than most taller cornerbacks. He also demonstrates solid route recognition skills, rarely getting fooled by double moves and consistently maintaining leverage against vertical routes. In press coverage, he uses his length effectively to jam receivers and redirect their routes early in the rep, further maximizing his physical gifts.
Despite his historic athletic profile, one of the biggest knocks on Porter has been his age. At 24 years old, he is one of the older prospects in the draft, which slightly limits his developmental upside. However, that same maturity gives him an advantage in terms of immediate impact. Teams looking for a defensive back who can contribute right away should view Porter as a prime target. His ability to step in and provide high-level special teams value while developing as a starting-caliber cornerback makes him a highly valuable prospect.
Before the combine, Porter was widely projected as a third to fourth round selection. However, his performance in Indianapolis has significantly boosted his stock. With a historic athletic profile and the ability to contribute immediately, he could very well hear his name called in the late second round by a team looking to infuse their secondary with elite speed, length, and versatility. However, he will most likely have solidified himself as a round 3 pick and day 2 selection. Ideal landing spots include the Buffalo Bills, Minnesota Vikings, and Cincinnati Bengals, all of whom could benefit from his unique blend of traits right away.
Darien Porter’s NFL Combine showing will go down as one of the most impressive in recent history for a cornerback. In a league that values elite athleticism, his historic numbers solidify him as a top regarded prospect, proving that he has the physical tools to excel at the next level.
