I wouldn't bother in redraft. However, I wouldn't be worried about Ware or Turbin long term.
Michael doesn't offer much versatility and isn't a big special teams contributor. With Lynch healthy, there isn't much incentive to make him active on gameday.
At some point in the future, Lynch will move on and Michael will take over as the preferred ball carrier.
question for you if CM is so good why hasnt he leap frogged Turbin for the COP/end of game occasional carry yet?
I dont think its a forgone conclusion that if Lynch got hurt that CM would be the back to own this season.
The backup in Seattle rarely carries the ball. Turbin is on pace for 72 carries. Almost inconsequential. What they seem to want out of their #2 is someone who can protect the QB and catch the occasional pass. Michael is not a great receiver. Turbin knows the offense and is a decent third down specialist for a bigger back.
Make no mistake, Michael is the future there. I liked Turbin okay in last year's draft, but he's simply not a very dynamic or creative runner. Michael can do a lot more with the same blocking and is far more of a big play threat. The reason you don't see him right now is because Lynch is occupying his future role.
2-3 years from now, it will be the Michael show. I think most Seahawks fans and homers will support me on that. He's just a lot more talented.
