The 2006-07 Mavericks went an absurd 38-2 between Dec 13 and Mar 11, finishing 67-15 — the best 40-game win % in NBA history. Then came the “We Believe” Warriors. An 8th seed led by Baron Davis, Stephen Jackson, and head coach Don Nelson shocked the top seed in Round 1, pulling off one of the biggest upsets ever. #NBA #NBADebate #NBAHistory #WeBelieve #Warriors #Mavericks #Sports
