This was from Feb 15th after Mavs beat Houston 106-102
"The Mavericks went 8-15 from three-point range. Dallas has now hit a three-pointer in an NBA-record 992 consecutive games. It is hard to imagine that the streak will end anytime soon with the league's third (Jason Kidd) and fourth (Peja Stojakovic) best three-point shooters of All-Time on the squad. Jason Terry is also in the mix as he is ranked eighth in that department."
So they passed it and I'm not sure how many games they have played since. You can count after the Houston win and see where they stand now.
