Chances are that this is a toss up so don't fret because each will likely put up similiar stats.
That being said. Personally, I really like White's matchup this week and think he will hit pay dirt at least twice. Plus he's in much better shape than years passed.
Cadillac would be my 2nd option. He looked agile and powerful in week 1 vs. the Cowboys.
LJ would be my 3rd choice. Until the KC offense can prove that they are better under new coach Todd Hailey, I'd avoid LJ. Plus Hailey is known more for his passing expertise w/ the cardinals rather that rushing game.
Go with your gut, and good luck!
