The Wade had too much LeBron James, too much Dwyane Wade and too much defense for Dallas tonight.
The testament as to how good the Heat defense was in that Dirk Nowtizki was reasonably kept in check (27 points but just seven of 18 from the field) while not leaving Dallas' jump shooters open (Jason Terry, Jason Kidd, DeShawn Stevenson, J.J. Barea and Peja Stojakovich were a combined nine of 32 from the field).
The Heat's defense isn't going to falter. If Dallas is going to win the series, though, the Mavericks are going to have to do a much better job of hitting contested shots and knocking in the very few wide-open looks they're going to get.
