O'Neill is a technical, high-motor edge rusher who compensates for below-average NFL measurables with exceptional pass-rush IQ, cross-body rush technique, and alignment versatility spanning the 4i to 7-technique. He torched lower-level competition — 90.4 PFF grade at JMU, 13 sacks in the Sun Belt — but the production cratered to 2.5 sacks when facing Big Ten offensive lines at Rutgers, confirming the athletic limitations scouts flagged. He's a situational pass rusher who can diagnose protections pre-snap and attack with precision, but he lacks the length, power, and speed to win consistently against NFL-caliber tackles. The floor is a special teams contributor who sticks on a roster through effort and intelligence; the ceiling is a reliable third-down rotational rusher if he lands in a scheme that weaponizes his positional versatility.
- Elite pass-rush IQ — diagnoses protection schemes pre-snap and attacks with calculated precision rather than raw athleticism
- Alignment versatility from 4i to 7-technique gives defensive coordinators a chess piece who doesn't tip his hand pre-snap
- Relentless motor and pursuit effort; consistently chases plays from backside angles when others quit on the whistle
- Good body control and flexibility to get low in his stance and explode off his quads; cross-body rush technique is a legitimate weapon
- Ascending career trajectory from FCS walk-on to FBS All-American demonstrates elite work ethic and football intelligence
- Below-average length, strength, and speed for NFL edge rushers — will not physically overwhelm NFL tackles at the point of attack
- Production collapsed against Power 4 competition: 2.5 sacks in 12 Big Ten games after 13 sacks in the Sun Belt, raising serious translation concerns
- Limited counter-move repertoire; relies too much on raw power and his signature cross-body rush — when the primary move is stalled, he has no Plan B
- Older prospect (redshirt senior) with limited physical ceiling and little projection remaining; what you see is likely what you get
Undersized, high-motor edge rusher who wins with effort, flexibility, and technique rather than raw physical tools. Both carved out careers as situational pass rushers and special teams contributors despite athletic limitations, making the most of their positional versatility.
