If what has been reported in the past 24 hours is true and Brady effectively told NE he wasn't coming back a year ago (which makes sense), then BB had last draft and this draft to get a top tier QB (and picked Stidham . . . this draft who knows). He also would have had the ability to plan for a year to free up cap room and make roster decisions to have cap space available to sign or trade for a known commodity (and has not). From what I have seen / heard / read, NE did not make any attempt to bring back Brady after Tom said he wasn't returning. They didn't even make him an offer (allegedly).
BB still could make a trade for a QB, make a trade to have room to sign a reliable QB, and draft a hot shot rookie QB. But SO FAR, BB hasn't done any of those things, which leads me to believe that Stidham will be the first option AS OF TODAY.
However, nothing would shock me, and they could cut or trade someone like Marcus Cannon to save $5.6 million in cap space (doubtful, but they have done weirder things in the past) or release Mohamed Sanu to save $6.5 million (who was said to have been someone Brady wanted around). It's still very early in the process, and as I always say with NE, we won't know much until we get to September.
