The train keeps on rolling!
Next up in our 90-in-90 series is Chargers rookie running back Greg Desroisiers Jr.!
The Basics
Height: 5’11
Weight: 200
College: UMass/Louisville/Memphis
Experience: Rookie
Desroisiers comes from Lawrence, Massachusetss where he starred at Belmont High School. His first collegiate stop was at the University of Louisville where he spent two seasons and made seven total appearances on game days. After taking a redshirt and COVID year, Desroiser’s third collegiate season, this time back
home at the University of Massachusetts, was technically just his redshirt freshman season.
That year, he played in 12 games and totaled just 210 rushing yards and two scores on 44 carries. His best game came against Liberty where he rushed for 110 yards and both aforementioned touchdowns on only seven attempts.
During the 2023 season, his second with the Minutemen, Desrosiers saw his opportunities stay consistent as he rushed 37 times for 185 yards and a career high four touchdowns. He also caught 15 passes and found the end zone twice through the air.
Desrosiers then transferred to the University of Memphis where he would spend his final two years of eligibility. In 2024, he was part of the Tigers’ 11-2 squad as part of their backfield rotation. He ended the year with 403 yards of total offense and seven touchdowns (three rushing, four receiving). In his final collegiate season, Desrosiers set a number of career high marks, including rushing yards (563), rushing touchdowns (seven), and receiving yards (228).
The Good
Desrosiers is coming off a 2025 season that saw him nearly hit a missed-tackle rate of 33 percent (.303). He shows a tenacity as a ball carrier and will scratch and claw to keep himself from losing yardage. Roughly 85 percent of his carries in 2025 were zone runs and so it’s safe to say the Bolts targeted him as a fit for their new offense.
As a runner, Desrosiers is very patient. It’s the type of patience that only comes with experience, even if his total carry count isn’t all that high. Six years in college will do that for you. He does not often bounce runs, instead preferring to put his head down and barrel through contact in order to not pass up a single or double in hopes of a home run.
While his top-end speed is middling (4.55), his 1.50 10-yard split (timed at Patriots local day) would have been the top mark at this year’s NFL Combine.
He also showed a knack for the pass game as he recorded a reception on over a quarter of his career touches and a third of his touchdown came through the air. As it stands, he looks to be a change-of-pace back at the next level.
The Bad
Desrosiers was never a starting running back during his six-year collegiate career. That happened for a reason and you have to think that puts a ton of history against him to find success at the next level.
He’s built well, but a 4.55 in the 40 is fairly “fine” for a player just a little over 200 pounds. This time would have ranked ninth at the NFL Combine among the 10 running backs who participated in the 40.
2026 Outlook
Desrosiers unfortunately will have a very tough time breaking through to find a place on the roster, and I believe that also extends to finding a spot on the practice squad, as well. Omarion Hampton, Keaton Mitchell, and Kimani Vidal are locked in as the three backs expected to be kept on the final roster. As for the PS, Desrosiers will have to compete with veteran Jaret Patterson and Amar Johnson. At the end of the day, I would be shocked if Patterson wasn’t once again kept on practice squad as the team’s emergency back.
