Rob Grosso begins his fourth season with the Packers and his first as assistant wide receivers coach after being promoted in 2026. Hired in 2023, he spent his first three seasons with Green Bay as an offensive quality control coach. Grosso (GROW-so) joined the Packers after serving as a defensive quality control coach for the Arizona Cardinals for four seasons (2019-22), where he assisted with the defensive backs.
In his first three seasons, Grosso was part of an offensive staff that helped the Packers rank No. 2 in the NFL over that span in sacks allowed (81), No. 5 in yards per play (5.8), tied for No. 5 in explosive plays (381), No. 7 in total offense (349.6 ypg) and No. 8 in rushing offense (126.2 ypg). In 2025, Grosso worked primarily with the wide receivers, helping WR Romeo Doubs post a team-high 55 catches for a career- best 724 yards (13.2 avg.) and six TDs. WR Christian Watson ranked No. 2 in the NFL with an average of 17.5 yards per catch and of his 35 receptions, 17 were explosive catches (16-plus yards), a 48.6 percentage that ranked No. 3 in the NFL (min. 30 rec.).
Grosso helped tutor TE Tucker Kraft, who was one of only two TEs in the league in 2024 (George Kittle) to post 50-plus receptions (50), 700-plus receiving yards (707), seven-plus receiving TDs (seven) and an average of 14.0-plus yards per catch (14.1), just the second Green Bay TE since the 1970 merger to hit those marks in a season (Paul Coffman, 1983). In 2023, Kraft (31-355-2) and TE Luke Musgrave became only the second rookie TE duo since the merger to both post 30-plus receptions, 350-plus receiving yards and a receiving TD (Patriots TEs Rob Gronkowski and Aaron Hernandez, 2010). Green Bay's tight ends ranked No. 1 in the NFL in yards after the catch per reception (6.8 avg.) in 2023-24.
Grosso was part of a defensive staff that helped Arizona rank No. 2 in the NFL in yards allowed per completion (10.10) in 2022, the top single-season mark by the Cardinals since the 1970 merger, and tied for No. 3 in completions of 20-plus yards allowed (40). S Budda Baker earned his fourth straight Pro Bowl selection, the only safety in the NFL to be named to the Pro Bowl each season in 2019-22. In 2021, the Cardinals ranked No. 7 in the NFL in takeaways (27) and No. 8 in offensive points allowed (349), and S Jalen Thompson was one of only three DBs in the league to post 100-plus tackles (team-high 120), three-plus INTs (three) and five-plus passes defensed (seven). In 2020, Grosso was part of a staff that helped the Cardinals rank No. 10 in the NFL in passing defense (226.4 ypg).
Grosso came to Arizona after spending the 2018 season with the Denver Broncos as the assistant to the head coach under Vance Joseph. Grosso also assisted with the team's outside linebackers and special teams. For the first time in team history, the Broncos featured two players with 12-plus sacks in OLBs Von Miller (14½) and Bradley Chubb (12). Grosso was elevated to the assistant position after serving as an operations intern with the Broncos in 2017.
Grosso worked with the Arizona Rattlers of the Indoor Football League during the 2017 season as a coaching/player personnel intern. He got his start in the NFL with Denver as a training camp operations intern (2015-16) before working as a volunteer assistant scout with the Saskatchewan Rough Riders (2016-17) and as a scout for Sports Info Solutions in 2016. His first coaching experience came at his alma mater, John Carroll University, when he served as a student coaching/recruiting assistant in 2014-15.
Grosso played wide receiver at John Carroll for three seasons (2011-13) and earned his bachelor's degree in business administration and management from the school in 2015. He was born Sept. 22, 1993, in Buffalo, N.Y., and grew up in Lackawanna, N.Y.
