Coach Greg Schiano said Wednesday that Williams made the decision after being told of changes to the running back rotation. Williams had started the first two games for the Scarlet Knights, but Rutgers has not played well in the run game. With true freshman Savon Huggins, Jeremy Deering and Jawan Jamison all in line for playing time, it became clear there was just not enough room to get everybody the carries that they wanted.
Schiano had said last week that he wanted to pare down his rotation to be able to establish more consistency. Rutgers is expected to move forward with Huggins as the primary ball carrier, a move that should help develop some trust and rhythm with the offensive line.
"We made some depth-chart changes and one of them were at the running back position and De'Antwan isn't agreeing with it, so right now he has decided to leave the team," Schiano said, according to the Newark Star-Ledger.
"But the door is open [for him to return]. We care a lot about him. I wish that he'd keep competing and stay at it but he feels like it's not right. As I said, the door is open if he wants to come back but he's going to come back to the way it is.
"He might want to go try someplace else, so we'll see."
Williams had a terrific fall camp, which led him to win the starting job. In an interview with ESPN.com last week, Williams said he was thrilled to be given that opportunity.
"Getting the start makes me believe and shows I put in all the hard work and it finally paid off. I felt like if I sat here and I gave it all I could give, I couldn’t be wrong. So I gave it my and all did everything in my power to do what I could do to get the starting job."
Williams had 20 carries for 59 yards this season.
