It's been a minute, but the Detroit Lions billboard brigade is back.
At least two billboards have popped up around metro Detroit — one reportedly on northbound I-75 around mile marker 55 and another on eastbound I-94 between Gratiot and Harper — showing a referee with a cheesehead on his head.
The billboard seems to imply the referees are Packers fans. Monday's 23-22 loss to Green Bay is mired in controversy. Controversial calls.
