It's not really clear what the message is, but we assume there's a message. That's the point of taking out a billboard.
Dave Birkett of the Detroit Free Press reports that an anonymous group of fans have posted several billboards in Metro Detroit and Grand Rapids with an ambiguous message about Lions star Ndamukong Suh, who the Lions would like to re-sign.
The Freep reports that several digital billboards read only "$uh?" in white print on a blue background.
Suh is getting ready to test free agency.
