I disagree somewhat. It's hard to expect an average QB to excel in the SEC...and likewise, until Chaney is given elite talent at RB, it's hard to expect our running game to excel. Can't blame him for leaning on our strength. If he tried to force the running game, people would be calling for his head in that regard as well.
You give him one or two RB's of that caliber and see if they don't become an integral part of this offense. That would open up the passing game, and likewise, the passing game would take some pressure off the running game.
I personally think Lane is the better RB overall. He doesn't have Neal's speed, but Neal doesn't have the toughness to break into the open field so he can use that speed.
