Shea Tierney is in his third season as the Giants' quarterbacks coach and his first with the additional title of offensive passing game coordinator.
In 2023, Tierney led a position group that cycled through three starting quarterbacks in Daniel Jones, Tyrod Taylor, and Tommy DeVito. A rookie free agent, DeVito improved enough under Tierney's coaching to start six games, winning three.
DeVito led Giants to victories at Washington and in home games vs. New England and Green Bay to become the first Giants rookie quarterback to win three consecutive starts since Phil Simms won four in a row in 1979. He was just the third undrafted rookie quarterback since the 1970 merger to win three starts in a season, joining Ed Rubbert, who won three strike-replacement games for Washington in 1987, and Pittsburgh's Devlin Hodges in 2019.
DeVito's passer ratings in those three games were 137.7, 103.9 and 113.9. He was the first undrafted rookie since 1970 to have three consecutive games with a passer rating higher than 100. DeVito was the first Giants quarterback since Eli Manning in 2014 to record three straight games with a 100-plus passer rating.
DeVito was selected NFC Offensive Player of the Week after leading the Giants to a Monday night victory vs. the Packers. He completed 17 of 21 passes (season-high 81%) for 158 yards, one touchdown, and no interceptions for a passer rating of 113.9 and added 10 rushing attempts for 71 yards. In the 74 seasons since the NFL began tracking starting quarterbacks in 1950, DeVito became the first starter in league history to complete at least 80% of his passes, rush for 70+ yards, commit no turnovers, and take no sacks.
He was the second undrafted rookie in the common-draft era (since 1967) with an 80+ completion percentage (minimum 15 attempts) in a game. DeVito's 71 rushing yards were the most by a Giants rookie quarterback in a game since 1960.
In 2022, Tierney's first year in his current position, Jones had the best season of his career, setting a Giants' single season completion percentage record of 67.2 and leading the team to its first postseason berth in six years and an NFC Wild Card victory in Minnesota.
Jones threw for 3,205 yards and rushed for a Giants quarterback-record 708 yards to join Philadelphia's Jalen Hurts and Buffalo's Josh Allen as the only NFL quarterbacks with 3,000+ passing yards and 500+ rushing yards. Jones threw a career-low five interceptions; he led the NFL and set a franchise record by throwing an interception on just 1.1% of his passes (5 in 472 throws). He led the Giants from deficits of 10+ points to victory three times in the season's first six games, tying him for the highest total by a quarterback in the first six games of a season since 2000.
Prior to joining the Giants, Tierney spent four years working with Brian Daboll on the Buffalo Bills' staff, the first two as an offensive assistant and the last two as the assistant quarterbacks coach.
In those two seasons, Josh Allen was one of the NFL's most productive and successful quarterbacks. The Bills were 27-11 combined in the regular season and postseason, won two AFC East titles and advanced to the 2020 conference championship game. In those 38 games, Allen threw for 10,405 yards and 87 touchdowns. He finished second in the NFL Most Valuable Player voting in 2020.
Tierney joined the Bills in 2018 after spending the previous two seasons as an offensive analyst for the University of Alabama, which was 27-2 when he was on the staff. With the Crimson Tide, he worked closely with Billy Napier, the wide receivers coach in Tierney's first season, who is now the head coach at the University of Florida. In his second season at Alabama, Tierney worked under Daboll, who was the offensive coordinator when the Crimson Tide won the 2017 national championship.
Tierney's first NFL experience was as a football analyst/coaching intern with the Philadelphia Eagles from 2013-15.
His initial coaching position was at North Carolina State as an offensive graduate assistant from 2011-12.
Tierney is a graduate of Neshaminy High School in Langhorne, Pa. and N.C. State. He is married to the former Emily Seng of Macungie, Pa. They have a daughter, Jordan.
