Seahawks beat writer Bob Condotta:
Eddie Lacy, Thomas Rawls and C.J. Prosise all are coming off of seasons when they had significant injuries and I think the Seahawks are going into the year just fine with the idea that they can spread the carries out and not have to count on anyone taking a Lynch-like share of the load.
My best guess, assuming they each are healthy, is Lacy and Rawls take a fairly equal share of the basedown carries with Prosise slated largely for a third-down role as well as being worked into the gameplan to take advantage of specific matchups from week to week.
So it sounds as if it's a possibility that Lacy is splitting time with Rawls on 1st and 2nd down, and that would indicate that the Seahawks will use a full-blown running back by committee. Lacy ran well last year, but that's no guarantee that he'll live up to his current 7th round ADP.
