History awaits Andrew Bogut and the Golden State Warriors while drama and disappointment continues to haunt Joe Ingles and his Utah Jazz.
The NBA's regular season ends on Wednesday (Thursday AEST).
If the Warriors, on their home court in Oakland, defeat the also playoff-bound Memphis Grizzlies they will eclipse the 72-win regular season record by the 1995-96 Chicago Bulls, featuring Michael Jordan and Australia's Luc Longley.
The Jazz travel to an emotionally-charged Staples Center in Los Angeles where 20,000 teary Laker fans will bid farewell to one of their greats, Kobe Bryant, who plays his last game.
To grab the eighth and final Western Conference playoff spot the Jazz need to defeat the Lakers and then hope the Houston Rockets lose at home to the hapless Sacramento Kings.
