Set By: Los Angeles Lakers
This record gets challenged every few years it seems, only what we call a "challenge" can hardly be considered that. The Rockets won 22 in a row in 2008 for the second best mark of all-time, but that's only two-thirds of the way there. Nobody is going to dominate again quite like the Lakers did; they didn't lose for two months and their average margin of victory was 17 points. Even the best teams can have off nights and lose to another good team. While it didn't happen to the Lakers, the odds of anyone replicating such a feat in the modern game are impossibly small.
