Patriots have a better chance than GB, IMO. Packers will face Cardinals and Denver both on the road. Sure, Peyton's arm looks like a noodle but they have a great defense. Cardinals are even better at home than Denver. If I had to pick a favourite to win the whole thing, I'd take the Cardinals right now.
Patriots D gets a lot of hate for some reason, but they are much better than advertised. And they will improve during the year as they always do. Pats went to SB a few years ago without a healthy Gronk and with zero defense. This team is much better than that.
The Patriots face Denver on the road as well. And between the Jets, Dolphins and Bills defenses, they have a much harder schedule than most give them credit for.
I don't really think GB has much of a challenge, although if the Bears game is representative of their away performance, then maybe you're right.
The secondary is still in flux for me to say it sucks. But it's not good. Malcolm Butler is doing excellent, but the drop between him and the no.2 corner is monstrous. I think Tarell Brown is the next best one on the roster. He is easily the most consistent at the position (and I'm pissed he dressed and didn't play, unless he was indeed recovering). Logan Ryan is mediocre and Bradley Fletcher is a liability. Justin Coleman looked decent. I'm surprised he hasn't made a trade for someone yet.
Defensive front looks good, and is going to get even better once Chris Jones returns.
Blount and Lewis is beautiful. We get LaFell back in Week 7 I believe. Really love what I'm seeing from the offense, and hope we can get Cadet, Chandler and 'dola more involved.
