Going back to 2012, NFL teams have selected 250 running backs in the draft, with 27 of those taken in the third round. The Los Angeles Rams have twice chosen backs in round three, in 2014 it was Tre Mason at #75 and in 2019 they took Darrell Henderson at #70.
Mason showed some promise as rookie, but struggled with personal problems and spent only two seasons (2014-15) with the Rams. In 2018, he made a comeback with the Canadian football League and had a solid season. Mason had nearly 1000 rushing and receiving yards, but suffered a knee ACL injury late in the season and it would prove to end his career.
