College Career (2014–2017)
During his redshirt freshman season in 2014, O’Neill adjusted to college-level competition while primarily focusing on development. After his position change to offensive tackle in 2015, he quickly demonstrated the physical tools and technical skills necessary to excel at the position. His consistency earned him a starting role that he would maintain throughout his remaining college years.
O’Neill’s performance at offensive tackle garnered significant recognition within the Atlantic Coast Conference. In 2016, he was named to the All-ACC Third-team, establishing himself as a formidable presence on Pittsburgh’s offensive line. His development continued in 2017 when he elevated his play to earn First-team All-ACC honors. Following his redshirt junior season in 2017, O’Neill declared for the 2018 NFL Draft, having completed his college career with 37 consecutive starts.
Pre-Draft Evaluation and 2018 NFL Draft
Leading up to the 2018 NFL Draft, O’Neill showcased his exceptional athleticism at the NFL Scouting Combine. He ran the 40-yard dash in 4.82 seconds, the fastest time among all offensive linemen at the event and the best time for a lineman since 2013. This performance also ranked as the fourth-fastest recorded time for an offensive lineman at the combine since 2006. Additionally, O’Neill recorded the best three-cone drill time among offensive linemen at 7.14 seconds, further demonstrating his mobility and agility for the position.
The Minnesota Vikings selected O’Neill in the second round with the 62nd overall pick of the 2018 NFL Draft. He joined a Vikings team that already featured offensive lineman Aviante Collins, who held the previous combine time benchmark. Upon joining the Vikings, O’Neill entered the season as a backup tackle behind established starters Riley Reiff and Rashod Hill. He made his first career start in Week 6 at right tackle after Rashod Hill was moved to left tackle to replace an injured Riley Reiff. O’Neill maintained that starting role for the remainder of his rookie season.
Minnesota Vikings Era (2018–Present)
Following his rookie season, O’Neill became a fixture in the Vikings’ starting lineup. His consistent performance and development as an anchor on the offensive line led to increased responsibilities within the offense. As he entered the 2021 season, O’Neill had established himself as one of the top offensive tackles in the league.
On September 8, 2021, the Vikings rewarded O’Neill’s performance by signing him to a five-year, $92.5 million contract extension. This deal made him one of the highest-paid offensive tackles in the NFL at the time. Following the 2021 season, O’Neill earned his first Pro Bowl selection, representing the Vikings in the all-star game and solidifying his status as a top-tier player at his position.
However, the 2022 season presented challenges for O’Neill. On January 3, 2023, he was placed on injured reserve and subsequently underwent surgery to repair a partially torn Achilles tendon. This injury sidelined him for the remainder of the 2022 season. Despite this setback, O’Neill demonstrated his resilience by returning to the field and continuing to perform at a high level.
Playing Style and Strengths
O’Neill’s exceptional combine performance translated directly to his playing style at the professional level. His combination of size, length, and foot quickness makes him particularly effective in pass protection. His 6-foot-7 frame and proven mobility allow him to handle speed rushers effectively while maintaining the strength to anchor against power players. His background as a former tight end provides him with body control and flexibility that distinguishes him from players who have played only offensive line throughout their careers.
Notable Achievements and Milestones
Throughout his career with the Vikings, O’Neill has accumulated numerous accolades. His two Pro Bowl selections in 2021 and 2024 highlight his consistent excellence. He has appeared in 124 career NFL games with 120 starts, demonstrating both durability and reliability when healthy.
