Sharing concerns/observations isn't spoiled, but I understand what you're saying. Seattle fans have had it very good for the last five seasons.
There is a sense an era is passing and I have to think more than a few on the team sense it as well.
Pete Carroll brought a championship to our city, narrowly lost a second one, and now, perhaps, is winding down his tenure here in Seattle. He has one year left on his contract, is already the oldest coach in the league, and certainly deserving of enjoying time away from the game if he so chooses.
I am more concerned with Wilson who does appear to be regressing somewhat instead of further developing himself as a top-tier QB. He's less secure, more spooked, inconsistent, and doesn't appear to have the full devotion of his teammates like he once did - or perhaps those teammates are more upset at some among the coaching staff? Hard to say there where that is originating.
Wilson is much heavier than he was a year or two ago - and that extra weight isn't helping him. It is once thing for a pocket QB to bulk up some, but a scramble/chaos QB needs to be FAST-FAST-FAST or they can't function. Teams come fully prepared to contain Wilson, and they are doing a better job of doing just that.
Now, if he was given a more competent O-Line, which would further establish the run game, and if Jimmy is further incorporated into the play calling, and if the great timing that currently exists between Wilson and Baldwin continues to develop, then that extra weight might not be so much of an issue.
That's a lot of "IF" though, and there will be a much bigger question mark at the end of this season than any season prior for quite some time.
