RB2 Starter - Hightower, Willie Parker, Jamal Lewis, LenDale?

I'd go with Parker. Pitt loves to run the ball.He had 3 tds and over 100 yards in week 1 last year. Hightower is in a p first offense. Arizona was at the bottom of the league at rushing attempts last year and Hightower had a horrid 2.8 yards per carry last year. Worst in the NFL last year.
