Not so sure to be honest. Brady was more of a hindrance than a weapon to them last season but you have to keep in mind that they don't have a pass-catching TE and their offensive weapons were average at best (their best WR is still Edelman and he's on the wrong side of 30 nowadays). Their ridiculously easy schedule and freakishly good D/ST won them games but they still crashed out in the WC round. Odds are that their D regresses to the mean this season and, unless they somehow get their hands on a great QB, their offense won't be able to win them games either.
They're still in competition for a winning record but they're quite far off the elite teams in the AFC for me, and if anything the gap will be bigger next season than it was during the last one.
