NFL Kickoff Sunday is underway, with the first slate of 1 p.m. games almost behind us. It's been an exciting day in the NFL to say the least, but it's about to get even better.

The highly anticipated matchup between the San Francisco 49ers and Green Bay Packers is set to kick off within minutes. Aaron Rodgers' Packers will host Patrick Willis' Niners at Lambeau in America's Game of the Week. 

A lot of folks are looking forward to the competition of great offense versus great defense. The Packers' O and Niners' D are both atop their craft as potential No. 1 units again in 2012. 

However, both teams have made significant upgrades to the opposite side of the ball. Green Bay spent its first six draft selections on defensive players, while San Francisco used the NFL Draft and free agency to add speed and explosiveness to its offense. 

In a potential NFC Championship preview, these two titans will clash in a battle for conference supremacy.
