I think so. Belichick hasn't been keen on developing talent through the draft the last several years, preferring free-agent acquisitions who've been in the system for a few years and are yet still coachable that he can plug into his own system. And it's been a very successful strategy. So I'm not going out on a limb in assuming that dealing Garoppolo for a 2nd round pick in 2018 affords him the ability to wheel and deal next season for another piece of their postseason puzzle.
I also think there's a push going on in NE right now to utilize Brady's availability the next couple of seasons to make another championship run, and since he's so much a part of their system - they undoubtedly feel that no other QB, young or old, could come in and duplicate what Brady does within the confines of their overall strategy.
And that "push" (imo) comes down to a realization that once Brady is no longer physically capable of holding down the fort in NE - what Belichick does really no longer matters, since he's not looking beyond that point in time within his own career. So why not gamble now, in hopes of perhaps acquiring the role players they need going into next season and the following season... I mean - if Brady went down - it really wouldn't matter who is under center for NE at the moment. Brady is the only player in the league who understands the limitations of his offense, who can also read defenses, and still figure out a way to win football games. If Brady goes down next week - the Patriots season would effectively be over, regardless of whomever is taking the snaps and running the offense.
Belichick/management is banking on Brady staying healthy.
And we shouldn't overlook the fact that Belichick is usually 2 steps ahead of everyone else in the league. If he felt Garoppolo was truly an incredible talent - he wouldn't have traded him at this juncture, especially considering that they could've gotten so much more from him prior to the start of the season.
The bottom line is that no one can replace Brady, and he alone shoulders the burden for NE the next few seasons. If they lose him - it really no longer matters. They've put all of their eggs in his basket, and who really could blame them given all that he's meant to this team over the years.
Belichick and Brady are on the 15th hole of the back-nine of their careers. They might sense that this season isn't their year to get it done. But they have a couple more seasons at-best to continue their dynasty of sorts and they're taking the needed steps to try to make that happen.
And as it relates to Garoppolo - I don't think he'll be a difference maker in SanFran anytime soon. Six quarters of football, however impressive it might've seemed against average teams with mediocre coverage last season, doesn't quite equate to bonafide stardom.
The verdict is still very much out on his ability to lead. And it wouldn't surprise me if he became another Brock Osweiler.
