What good would those types of guys do us? Yes, I would much rather go with Randle, Williams, and one of the top rookies.
RB is one of the easiest transitions from college to pro in football. If you're good, you are usually good right away.
What good would they do? Totally depends on what role they have and how much they have to play, but it could end up doing plenty of good.
I think there is a pretty good chance Randle isn't even on the roster when the season starts. He's a moron that they can not rely upon. They seem to like Williams as a practice squad safety net, but I don't think they are at all comfortable with him assuming any kind of major role. If they are prepared to make him that cheap vet then fine by me. I'm just not sure they are.
I'm all for going the rookie route. Draft a talented young player to come in and be the guy. But personally I would part ways with knucklehead Randle and sign a proven vet to a 1-2 year deal at $1M per year or so with very little guaranteed money. This team is not a rebuilding project, they are trying to contend for a Super Bowl in a small window of time while they still have Romo at QB. I would not take a chance on misevaluating a rookie in the draft to find out he isn't a very good NFL player, or that he gets hurt, or that he struggles in pass coverage and risks getting Romo killed. They should cover their asses with a RB that has proven himself at the NFL level.
