Which teams are riding into the 2012 NFL season with high expectations, and which teams are not getting major publicity during the offseason but could make a major impact this fall?

NFL Lead Writers Josh Zerkle and Matt Miller break it down, giving you the low-down on which teams are playing with major pressure to perform and a few candidates to go from "worst-to-first."

The San Francisco 49ers had an improbable run through the 2011 season, taking them all the way to the NFC Championship Game. With a Super Bowl berth so close, the 49ers enter the season as favorites to make it back this fall. Can they rise up to those expectations?

In Philadelphia, the Eagles were dubbed the "Dream Team" last year, and that pressure—along with holes in the defense—led to a horrible start and an 8-8 finish. The Eagles patched those holes in the offseason, but can they overcome the pressure of being a national target?
