Ollison didn’t play on any of the Falcons’ special teams units.
Gallman, who’s from Loganville and played at Grayson High and Clemson, was a fourth-round pick of the Giants in 2017. He has rushed 336 times for 1,444 yards (4.3 avg.) and scored nine touchdowns over four NFL seasons. He also has caught 80 passes for 498 yards (6.2 avg.) and two touchdowns in his career.
Gallman, who’s 6-0 and 216 pounds, most recently was with San Francisco.
Ollison, a fifth-round pick in 2019, showed promise as a short-yardage back in his rookie season, but played sparingly in 2020 because the former staff thought he was a liability in pass protection.
