Absolutely. The Cowboys are a talented bunch but they are mentally weak, they shrink in the moment. The Colts, Steelers, and (at full strength) Eagles are teams I can think of that are usually consistent, and have that extra gear they can kick into when their team is trailing.
Even last year, there were a handful of games (@ Colts, Eagles, @ Ravens, @ Giants) that the Patriots very well could have lost, but with great determination, and a little luck, found a way to win every time. This year those types of games will probably result in losses, as we can't honestly expect the Patriots to play at the level they did last year. But we can certainly hope that they do, and then some.
Also true. For the sake of my own sanity, I like to think about the next game and that's it. Looking too far ahead means you can lose sight of what's in front of you. I want to savor these games more individually, instead of being caught up in the "when does the Super Bowl start?" frame of mind. I didn't enjoy last season as much as I maybe should have, but that's for a plethora of reasons I rather not bother to rehash.
