ESPN Insider asked several of its expert analysts -- Jay Bilas, Fran Fraschilla, Seth Greenberg, Joe Lunardi and Miles Simon -- to update their Final Four and national championship picks for the 2012-13 season now that conference play is underway. We've listed their answers below. For a look at their picks in the preseason, click here.

Jay Bilas

FINAL FOUR

Louisville Cardinals: The Cards have the best defense in the country, super-quick and disruptive guards, excellent depth and a better team overall than last season's Final Four unit.

Duke Blue Devils: If healthy, and that is an "if," with Seth Curry gutting out a leg injury and Ryan Kelly out indefinitely with a foot injury, Duke will be a No. 1 seed because of its quality of wins. This team can really stretch the defense. The only concerns with Duke are defensive rebounding and depth.
