A marathon of basketball

No, North Carolina is not playing today, but there's no reason not to get your fill of college hoops.

ESPN is currently in the midst of 24 hours of college basketball -- a marathon of dunks and defense (and maybe a buzzer-beater or two?) to whet our appetites for the rest of the season.

Here's Eamonn Brennan's primer (and schedule of games).

And beginning at 10 a.m. ET, there's Tip-Off Marathon Live, where we’ll be following all the games until the final one ends sometime around the midnight hour. So stop by and chat.
