It's impossible to analyze running backs without considering run-blocking, so we'll combine them. Okay I've combined them.

RUNNING GAME

Adrian Peterson is arguably the most gifted running back in the game and he's anchored by a fear-inducing left side of the offensive line.

Ryan Grant looked like a bona fide All-Pro down the stretch and the Packers have maintained one of the most consistent lines in the game for years, keeping their former quarterback healthy all these years.

So now we get to the Lions. Both will be starting a rookie at the tackle position (Williams, Cherilus). Both will be starting a mid-range player at the other tackle (Tait, Backus). Neither has a stud guard. We have a stud center.

As for the actual runners...well...ugh. Here's what the Lions offer.

Bell, Tatum
Calhoun, Brian
Cason, Aveion
Ervin, Allen
Pinner, Artose
Smith, Kevin
Bradley, Jon
Felton, Jerome

...so let's just say we're 3 1/2
