From the way this season has started I don't think you're going to see any teams that stand out as "Goliaths", at least not in the way the Colts, Saints and Vikings did last season. Here it is only 4 games in and the only unbeaten team left is the Kansas City Chiefs. Even the teams with 3-1 records have already had weaknesses exposed that opponents can exploit. 13 teams are at 2-2 right now. There are some, like the Jets, Falcons, Chargers, Steelers, Packers, Ravens and Patriots making early season runs at "better than the rest" status but even they look vulnerable to what might be called "second-tier" teams. And most of the 3-1 teams have had very close escapes already. Unless a few teams bust out by mid-season and go on 5 or 6 game streaks-not impossible, mind you-we could look at a major traffic jam for playoff spots come the last quarter of the season.
This season, so far, looks less like "good" teams versus "bad" teams and more like what team component match-ups look like.
