This is a competitive profession, and teams are always, always, always supposed to try to find the best players they can at every position they can.
When the defense and particularly the defensive line is as atrocious as it was last year, not a single player on that defense should be surprised if they're cut loose at any time this off-season.
I'm sure Woods was expecting a chance to at least compete, but that's the way it goes sometimes when the team is trying to improve from a rock bottom performance from your unit, they brought in some younger talent, and there's a numbers crunch in relation to the roster limit and the salary cap.
