Minor weaknesses dot these teams. Except for Arizona, which needs to bring in more help to really run Bruce Arians' offense.

Not because he's a bad player, of course. He looks like a great player. But with the way today's offenses are built on disguise and deception, teams don't need great left tackles to win. They just need "good enough" left tackles, and a look at the last ten conference champions paints a clear picture.

It's time for Christian Ponder to take the leap. Does he have enough weapons to make that happen? Will this club tab a middle linebacker early in the draft?

Was the thrashing against San Francisco in the playoffs a one-game fluke, or a sign of underlying problems? And can this team possibly build an offensive line worthy of its quarterback?

Will the pieces around Calvin Johnson stay healthy this season? Can the Lions secondary and pass rush get back on the right track with some offseason tweaks?

Lovie Smith and Brian Urlacher are gone. How will Marc Trestman and Mel Tucker change things in Chicago?

The coaching staff got the best out of this team in 2012, but will they need to change the system to keep RG3 healthy?

New coach, new team. (But don't call it a dream!)

The Giants faded down the stretch last season and missed the opportunity to spoil the party in the playoffs as has become their custom. Can they return to the dance this year?

Can the Cowboys finally ... well ... stop being the Cowboys?
