I really hope they don't spend big in free agency. They don't need to. I'd really like to see Kam extended, ASAP. Then, keep rolling that cap forward.
We are eventually going to have to 'pay the piper' for paying Russell Wilson, Richard Sherman, KJ Wright, Brandon Browner, and Doug Baldwin relatively nothing. The Seahawks are paying their probable franchise QB and an All Pro CB about 1 mil/yr... combined. (http://www.spotrac.com/nfl/seattle-seahawks/yearly/
The guys listed by the OP are fine players, but for someone else's team. However, I do understand the allure of Amendola considering that it seems like he kills us.
