It marks the 15th straight campaign the Spurs have reached that plateau, the best stretch in NBA history. (The Lakers are second with 12 in a row, from 1979-80 to 1990-91.)
1999-00: 53 victories
2000-01: 58
2001-02: 58
2002-03: 60
2003-04: 57
2004-05: 59
2005-06: 63
2006-07: 58
2007-08: 56
2008-09: 54
2009-10: 50
2010-11: 61
2011-12: 50 (shortened season)
2012-13: 58
2013-14: 50
But for the 1998-99 lockout, after which the Spurs won 37 of 50 games for the third-best win percentage (74.0) of the Duncovich era, they’d almost certainly have 17 straight 50-win seasons. (The Spurs won 56 in 1997-98, Duncan’s rookie season.)
Pretty amazing streak. We truley are spoiled.
