San Francisco 49ers defensive end Cassius Marsh said he hated playing for the New England Patriots so much last season that he considered quitting football.

Marsh was acquired by the Patriots from the Seattle Seahawks last September in exchange for fifth- and seventh-round draft picks. Known as a pass-rushing end, Marsh said he was miscast by the Patriots as a coverage linebacker. He became so disenchanted with his role that he requested a meeting with coach Bill Belichick that he hoped would result in being waived by the team.

"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 San Francisco 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."
