Carroll added that general manager John Schneider has devoted a "tremendous amount of effort into the long view," with the intention of maintaining a nascent dynasty.
The Seahawks will be tasked with "some really difficult decisions" in the offseason, Carroll acknowledged.
The Seahawks have built an uncommonly deep and talented roster with a considerable competitive advantage of Wilson's minuscule contract.
As is customary in professional sports, staying on top is a greater challenge than getting to the top.
