NEWARK -- Wide receiver Brandon Marshall has been part of the conga line of veterans to exit Florham Park this offseason.

The Jets continued to purge their roster on Tuesday with the release of middle linebacker David Harris and the announcement of a plan to either cut or trade wide receiver Eric Decker. The Jets already had cut ties with Marshall, cornerback Darrelle Revis, center Nick Mangold, tackle Breno Giacomini, tackle Ryan Clady, safety Marcus Gilchrist, linebacker Erin Henderson and kicker Nick Folk to clear significant salary cap space.

Marshall has no bitterness toward the Jets. After his release, the six-time Pro Bowler joined the Jets' MetLife Stadium co-tenants, the Giants.

With Marshall now in position to compete for a Super Bowl and the Jets among the early favorites to land the No. 1 pick in the 2018 draft, Marshall offered support in his former team's approach.

"I think they have some great football minds there in Coach (Todd) Bowles, the general manager (Mike Maccagnan) and even some of the guys and ladies underneath them. So they obviously have a plan," Marshall said on Tuesday while accepting a $50,000 donation from the NFL and United Way of Essex and West Hudson to benefit his Project 375 foundation. "It doesn't seem like they're going to win a championship tomorrow, but I think that they're headed in the right direction. To make progress sometimes it's painful and sometimes you've got to take a step back. But I believe in that team - team being Coach Bowles and his staff and the people upstairs, the guys that we call the suits."

Tuesday was technically Marshall's last matter of business as a Jet. He earned the $50,000 donation for Project 375, which is dedicated to mental health, as a result of his selection as the Jets' 2016 Walter Payton NFL Man of the Year.

"We can't do it alone. So to be able to partner with United Way of Essex and West Hudson, United Way Worldwide, the New York Jets - those are phenomenal organizations and everyone knows them," Marshall said. "For them to recognize what we're doing and bring us along says a lot. The NFLPA and the NFL do a phenomenal job of really helping the guys that are doing great things in the community. Without them, we wouldn't be able to make the impact that we're making. It's great to represent the New York Jets today, although I'm a Giant now. But community and the work that we do in our community goes far beyond the playing field."
