Partly thanks to coach Rick Carlisle's meticulous end-game sets, and sometimes because they've just been lucky, the Mavs have won 10 consecutive one-point games.
The feat ties the NBA record set by the St. Louis Hawks in 1960.
Against the Bucks the Mavs improved to 30-15 and survived when Carlos Delfino's runner caromed off the back rim in the final seconds. Not sure that Erick Dampier altered the shot, but he was definitely in the neighborhood.
So ...
Are we impressed with the Mavs' mettle, with these games steeling their resolve toward playoff nail-biters?
Or are we alarmed that Dallas is struggling to squeak by sub-.500 teams at home?
