Mason didn’t play at all last season as he dealt with an array of personal issues. The Rams placed the running back on the reserve/did not report list after he failed to show up to an August meeting, and subsequent reports indicated that he hadn’t contacted the organization in months.
Last March, Mason was arrested for reckless driving, resisting arrest, and possession of cannabis, and he was “admitted for evaluation” in July following an incident at his mother’s house. Former coach Jeff Fisher had expressed concern for his well-being, while tackle Greg Robinson said the player changed his phone number.
The 2014 third-round pick appeared in 25 games for the Rams (12 starts) during his first two seasons in the league. He collected 972 rushing yards and five touchdowns on 254 carries, and he added another 34 receptions for 236 yards and one score.
Meanwhile, Watts was suspended indefinitely in November after once again violating the league’s policy on substances of abuse. The former undrafted free agent ultimately played in 15 games with the Rams, compiling 48 all-purpose yards.
