During a gaggle with reporters Tuesday, Richardson said the "locker room is a whole lot easier to get along with now."
He joked, when asked why: "Let's just say we've got 15 reasons why it's better."
For all those amateur detectives out there, 15 is Marshall's number.
Given that Marshall plays for the New York Giants now, it didn't take long for someone to reach out to the veteran receiver. Marshall, however, would not let the spark turn to flame.
"Last year was an extremely difficult season for all of us," Marshall told Newsday's Kimberley A. Martin. "Players and coaches fought their tails off trying to get our season turned around and it didn't happen for us. It was disappointing, but now it's a fresh year for Sheldon, for myself, for the Jets, and now I'm a Giants and I'm so excited for this opportunity.
"I'm working my butt off to learn the plays. It's like I'm starting all over again from scratch. I feel like a rookie, and I kind of like that feeling. And hopefully, I can do my job this year to the best of my ability to bring that Lombardi Trophy back where it belongs."
But for the Jets, this has to be another disappointing check in Richardson's folder. He already has been suspended for violating the NFL's personal conduct policy (one game, 2016) and its policy on substances of abuse (four games, 2015). Richardson also was benched last season in November. His comments seem harmless and funny, though a team waiting for Richardson to turn the corner might think otherwise.
One could see how Marshall's grandfatherly act could wear thin -- Odell Beckham might find out the hard way -- but it seems like the Jets want nothing more than for Richardson to fall in line and start performing up to his capabilities. When healthy, the Jets have one of the top three defensive lines in football, though Richardson went from 11.5 sacks in his first two years to 6.5 in the last two. A renaissance both off and on the field could earn him a lucrative deal from a team looking to utilize his versatility and interior pass-rushing skills once his fifth-year option term is up.
