Just in case anyone was concerned that Detroit got better by signing washed up RB Rudi Johnson, don't be. According to Football Outsiders, in 2007, Johnson was real bad. Signing Shaun Alexander would have been a worse move, but it would have been better to have signed former Bear Cedric Benson. Or just have kept RB Kevin Jones. Hell, even RB Tatum Bell is better, except you have to watch your bag when Bell's around. Not that any of these moves would have helped Detroit, and anybody would have been behind rookie RB Kevin Smith on the depth chart.
It makes me glad GM Ted Thompson doesn't waste any time with pointless roster moves on has been players.
