Todays' top sports stories:

The "First Four" games in this year's NCAA Tournament begin tonight, with North Carolina A&T facing Liberty for the 16 seed and St. Mary's vs. Middle Tennessee for the 11 seed. Both games are part of the Midwest regional. [Washington Post]

The Miami Heat ran their second-best-ever winning streak to 23 games last night with a win over Boston. One oddsmaker gives them a 6-to-1 shot at breaking the all-time record, held by the 1971-72 Lakers. [S.I.]

Former star NBA player Adrian Dantley has quite the unusual post-basketball job: he's a crossing guard in Silver Springs, Maryland. (Not a sad story of a broke former athlete, by the way. Give it a read.) [Deadspin]

Did you see that absurd, out-of-this-world dunk that LeBron James threw down over Jason Terry? Well, it seems the dunk may have actually killed Terry. [USA Today]
