For me, the bigger and better aspect of this is that he's returned the Patriots to being one of the top teams for free agents.
He's done this in less than one season (no matter what happens from here) and rather than waste all their cap space last year when they had to overpay, they wisely opted to save that for later, when they would presumably return to respectability. We all know that the Pats were snubbed by various high profile free agents this off season.
At the very least that's a thing of the past.
As it stands I can see some players actually taking a discount to play here, so as good as we are, we're on the path to greatness when we'll see some additional upgrades and signings.
So this isn't just a one year thing - this is turning around a big ship that had quickly sunk into one of the teams players DON'T want to play for - Vrabel has really rescued the franchise.
