The reaction when Lebron passes a ball at the end of the game being so hysterical is a really sick result of modern media coverage, like with the Tebow obsession except it never ends ._.
Mavericks are still a real contender because of their strength on back to back road games, which comes into play during playoffs. Obviously it does not STRICTLY matter - last season Heat were #1 and Mavs were #3 at this (before playoffs). This year the teams are doing it at a crazy rate...last year Mavs were #3 at 65%, the year before THAT Mavericks were #3 at 65% (Celtics and Lakers 5/6), and the season before that with the Cavaliers, Lakers, Magic, and Celtics at 68%+ two of them made the finals, the season before that Lakers and Celtics 2/3 above 65% and finals....the biggest failure year was 2006-2007 where the Mavericks and Rockets were both over 80% in these situations and irrelevant in the playoffs, with the infamous round 1 collapse for the Mavericks :/
