If Gronk is out for any extended period of time I don't know how they absorb the loss of their starting RB, WR and TE. Brady is great, but there are limits to what he can do if he doesn't have a running game and no one to throw to. I will be first to admit that I have been impressed with them staying undefeated up to this point. They have shown me more than enough this season and the last fifteen years that their organization knows how to develop players, prepare better than other teams and win.
