Back spasms slowing Lynch in Seattle
Regardless of if he is simply resting or not, this shouldn't overly concern the Seahawks. After dealing with his back issues last year, Lynch averaged 96 yards and one touchdown per game for the remainder of the season. Lynch should be set to go by the opener, and hopefully he'll light it up like he did down the stretch last year.
The one thing that could cause concern in Seattle is that Lynch has lost seven pounds since last year in an effort to gain quickness. Obviously, Lynch's past success hasn't come as a result of quickness, and his size compliments his vicious running style. Already dealing with an injury, Lynch's lighter body may not be able to hold up through a full season of beast-mode, though I would still guess that it will.
From a fantasy perspective, don't drop Lynch down your board at all. He's still a good value in the second round and has the potential to improve on last year's numbers, now playing in what looks to be a more dynamic offense. One would be wise, however, to draft backup running back Robert Turbin in the later rounds, just in case these back issues linger.
