We ran a couple straight downhill plays with Jonathan and you could see everybody kind of pick up after that point. He had one year remaining on his contract.
Releasing him creates $3.7m in cap room for the Panthers.
Earlier this week, the team also released veteran safety Kurt Coleman and defensive end Charles Johnson.
Stewart, the Panthers' all-time leading rusher, was selected in the first round of the 2008 NFL Draft and played every snap of his 10-year career with the team.
While Jonathan Stewart put in the work, he has not been a 1000 yard Running Back since his second season with Carolina in 2009. He has 7,318 career rushing yards on 1,699 carries, also a franchise record. Without Russell Wilson's scrambling and team-leading rushing yards, the league's 25th-ranked run offense last season would have been last, by far. "I just started watching tape on that group, so I don't really have a feel for them, but I do think there is a guy that could potentially help us".
At age 30, Stewart would be cheap on what would likely be a low-risk, short-term deal for a Seahawks team that is tight against the salary cap. Stewart made the Pro Bowl in 2015, the same season the Panthers made Super Bowl 50. Stewart averaged a career-low 3.4 yards per carry (680 yards on 198 carries), and his total yards were his fewest since 2013, when he was limited by injuries. It was not for pretty much the last decade.
With Norv Turner running Carolina's offense for the 2018 season, Rivera is confident that no matter who the Panthers plug into the scheme, the veteran play-caller will get the most out the running back position.
