Ricky ProehlWhat we're watching: With just four teams left vying for two Super Bowl spots, it's all about the high-def pigskin today. The AFC game between the Steelers and the Broncos kicks off at 3 p.m. on CBS. This game is in 1080i, while the NFC game is in 720p. Fox goes deep in their NFL coverage starting at 6:30 p.m. with the Panthers pouncing on the Seahawks. Let's forget which teams we want to win for a sec; after you watch a little (or all) of each, drop us a comment with your thoughts on the whole 1080i vs. 720p fight. Regardless of the progressive nature that helps sports programming, I'm personally still a 1080i guy as the picture looks clearer to me. How about you?
