What are Chargers Getting with UDFA RB Greg Desrosiers Jr.?

The Los Angeles Chargers signed former Memphis Tigers running back Greg Desrosiers Jr. as an undrafted free agent following the 2026 NFL Draft, adding another layer of competition to a crowded backfield behind Omarion Hampton, Kimani Vidal and recently signed free agent Keaton Mitchell.

The Lawrence, MA native spent the first two seasons of his college football career at Louisville, where he failed to record any offensive statistics during his tenure.

Desrosiers transferred to Massachusetts in 2022, recording 210 rushing yards on 44 carries and two touchdowns, along with 8 receptions for 24 yards. He followed that season with 301 rushing yards on 37 carries for four touchdowns, along with 15 receptions for 185 yards and two touchdowns through the air. In 2023, he earned a career-high 82.3 overall offensive grade from Pro Football Focus, with an 84.5 rushing grade.

He spent his final two seasons at Memphis, recording 228 rushing yards and three touchdowns on 31 carries, along with 21 receptions for 175 yards and four touchdowns in his first season with the Tigers. Desrosiers finished his senior season in 2025 with 563 rushing yards and seven touchdowns on 99 carries, along with 228 receiving yards and  one touchdown on 32 receptions.

At his Pro Day, Desrosiers measured at five-foot-11, 202 pounds with 29 inch arms and 8 7/8 inch Hanes with a 71 3/8 inch wingspan. He ran a 4.55-second 40-yard dash, a 2.59-second 20-yard dash, a 1.50-second 10-yard split, a 7.02-second three-cone drill, along with a 34 1/2 inch vertical jump, a 10-foot-one-inch broad jump and 18 bench press reps of 225 pounds.

Desrosiers fits well with the Chargers due to his versatility and ability to contribute in multiple areas of the offense, both on the ground and as a pass catcher. His acceleration and one-cut running style allow him to get downhill quickly, while his receiving ability out of the backfield could give the offense another option in passing situations and the screen game.

His experience handling a variety of responsibilities at UMass and Memphis, including contributing in space and operating in tempo-based offensive concepts, could help him transition into a complementary role at the next level.

Special teams could also become a pathway onto the roster or practice squad early in his career. With the running back room featuring significant competition and depth, Desrosiers enters a situation where strong training camp performances and versatility could help him carve out an opportunity.
