To address a problem that was costing NBA owners money and NCAA programs players, the NBA drastically changed their eligibility policies in 2005, essentially requiring players to play a year of college basketball before they could declare for the pro draft.
On national TV's sports news, the two smokin'-hot teams have been basketball's Miami Heat (beating almost everybody theyplay) and hockey's Blackhawks (kinda sorta technically not losing to anybody theyplay).
