The NCAA Tournament officially begins in one hour, when UNC Asheville takes on Arkansas-Little Rock for the right to lose to Ohio State. (If nothing else, consider it a chance to locate truTV on your television.) Then there’s another game after that, and two more tomorrow to close out what’s technically the tournament’s first round. But, you’re wondering, how do these games affect your entry in The Sports Section’s NCAA Tournament Pool? Glad you asked! (We will assume you just asked that question, out loud, to your monitor.) You don’t need to pick the winners of these games, so you can go ahead and make your selections now. Of course, should their outcomes affect your strategy for the other rounds, you can edit your bracket until 12:15 p.m. Thursday. And if you haven’t joined the pool yet — winner gets to write a post on whatever they’d like — click here to sign up.
