Lace up those dancing shoes. It’s time to boogie.

Men’s March Madness officially begins today, with the 64-team first round tipping off at 12:15 p.m. ET. Before the guys and gals hit the hardwood, co-hosts Steph Rotz and Lauren Tuiskula are going all in with a Big Dance primer, spending this episode of The GIST of It talking about the top storylines in the men’s and women’s tourneys. Gimme gimme, shimmy shimmy.
