All that is being discussed here is a method to increase your talent in the short term by putting some of the cap value on the team credit card where it can be paid off down the road in easy installments. It is very appropriate for teams that they think have a chance to compete for a championship right now if they could just spend a little more, and they are willing to make their team worse a few years from now in order to get that immediate bump in value.
Are the '14 Seahawks one of these teams?
If you tend towards extreme pessimism then we may be losing Sherman and Thomas after this season, Russell Wilson after 2015, and our draft picks in the interim may all bust. If you believe all that then it makes a ton of sense to do a lot of contract restructuring this offseason to not only retain Tate/Baldwin/Rice and Bennett but also to bring in maybe a split-end like Kenny Britt as insurance for when Rice gets hurt.
More realistically, Carroll's system will continue to develop good secondary players. Some of our other draft picks will turn out to be good, and Wilson will remain with the team that drafted him and where he won a Superbowl. In this scenario, I don't think it makes much sense to rob from the 2016 Seahawks in order to pay the 2014 Seahawks. If you plan on being a season ticket holder in 2016 you probably have a similar opinion.
