The best way to look at this is to split offense and defense 50/50 after taking our practice squad, IR, etc money.
If you look at it equally, there's plenty left to sign RW, Carp and Sweezy on offense this offseason. Possibly even a big FA TE.
On defense, these moves and the Wagner extension make it very difficult to retain Maxwell. It's very hard to pay all four of your starting DB's unless you gut another position group. Also Simon is ready to step in next year and Maxwell is making a lot of money right now by playing outside and also the nickle thus increasing his value via flexibility. My guess is he ends up around 6m a year.
This bodes very well for the continuity of our offense and defense going forward. The shipping of of Harvin allowed this to happen this year instead of in the offseason preventing any hesitations by players to test free agency. Also we're taking care of our own which is what we said we'd do and if players play and act the right way, this is a good sign that we'll take care of you.
Overall this is just how you could see it playing out as you look at these things from a macro perspective. The players want to be here and they're getting rewarded with their play and professionalism. I couldn't be happier that our core on offense and defense will be here for at least 3 more years and we'll keep our super bowl window open for that time at the minimum which is very difficult in today's league of free agency and parity.
Go Hawks! What's next? Wagner's next!
