Randle ran for 6.7 yards per carry. Tough to call that a 'drop-off.'
The issue is more about what pace can Murray sustain and at what price?
If he's running more like a $3 million a year tailback and we were paying him $8 million, that's not as good as if we get McFadden or Randle or Williams to run like a $3 million tailback at a much lower price (McFadden's contract is obviously almost all incentive based).
I think expecting Murray to even run for 1,500 yards, even if he was with the Cowboys this upcoming season, is very optimistic. So I don't think you can assume that Murray was going to get those 'tough yards.'
I'm guessing Randle's job is probably safe because I don't think McFadden or Williams can play ST. It's just a case if he can win the #1 spot or not. Or they may do a little more of a RB by committee thing. It may not be a 50/50 carry thing, but a 60/30/10 between say, Williams/Randle/Dunbar.
The big thing here is I think we have potentially 3 very capable #1 tailbacks in Williams, Randle and McFadden and I think each will get a legitimate chance to win the #1 spot and usually in the NFL, legitimate competition tends to work out positively in the end rather than forcing a starter to continue to start simply because of their contract dictates them having to start.
