Seemingly nobody is off the Ravens' board.
In John Harbaugh's season-ending news conference on Thursday, the Baltimore Ravens head coach noted the importance of adding playmakers to his offense, but he didn't turn down the possibility of adding depth to other positions.
"Alex Collins has proven he can be a very good back in this league," Harbaugh said. "These [running backs], yeah I think they are good enough, but I'm all for adding a guy in that position if I think it makes us better."
Harbaugh has also said he wouldn't be opposed to bringing in a quarterback.
