Cassius Marsh wanted out.

The New England Patriots traded a fifth-round pick for Marsh during the 2017 offseason with hopes of getting a big year out of the defensive end. But he simply didn’t fit on the field or off it. The team and Marsh parted way after Marsh got just two snaps against the Oakland Raiders in Week 11.

On the surface, Marsh’s departure didn’t seem acrimonious. But appearances aren’t everything.

“I confronted (coach Bill Belichick) about all the things that were going on,” Marsh told the San Francisco Chronicle’s Eric Branch. “I won’t get into detail, but it was B.S. things they were doing. I just wasn’t a fan. And so I, basically, without asking to get cut, I kind of asked to get cut. … I had confidence that I would have an opportunity elsewhere and I would take advantage of it.”

Marsh told the Chronicle he “wanted to get waived.”

And perhaps he was right to want a change of scenery. The defensive end never made much sense in New England’s scheme. He was a miscast from the beginning.

“They asked me to do a bunch of stuff that I had never done: covering running backs and receivers and basically almost never rushing the passer, which is what I did in playing defensive line,” Marsh told the Chronicle. “They don’t have fun there. There’s nothing fun about it. There’s nothing happy about it. I didn’t enjoy any of my time there, you know what I’m saying? It made me for the first time in my life think about not playing football, because I hated it that much.”

Marsh’s criticisms of Belichick come after the coach led the Patriots to Super Bowl LII, where they lost to the Philadelphia Eagles. An uncomfortable offseason has ensued, as Tom Brady and Rob Gronkowski have skipped the voluntary practices during offseason team activities. Brady is the only healthy starting quarterback in the NFL skipping OTAs.

In most offseasons, Marsh’s comments would not carry much weight. But at a time when speculation is swirling about Belichick’s methodology, Marsh has added fuel to the fire.
