I would have rather got Terrence West but if they had to get a relatively young back, we shall see with this player. Just inconsistent as can be, but if he were not he would not be available. Just makes you wonder when the two time defending conference champions give up on him.
I think part of it is the fact that Michael will not be on the field all the much until Lynch is gone, and Michael's contract expires before Lynch's does.
I think it would take a really large drop off in production for Lynch to be out after 2015 which means the best case scenario for Michael's playing time would be part of 2016 just before he's a free agent in 2017. The other part is that he probably hasn't developed as much as they would hope. That's fine. He'd have to be pretty damn good to take carries from a guy who gets 1300 yards and 12 TDs every year.
Little prospect to play because of an established, productive player ahead of him and possible lack of progress to some extent. I think it's understandable.
That said, I don't really care why. The Seahawks have a damn good running back and Dallas does not. He may not be good enough to help their running game but it's hard to imagine he can't serve as an improvement over the wildcards Dallas currently has. More importantly, it's hard to imagine he's not a better option than the random the team will have to sign when one of the wildcards gets hurt.
