A season that started with championship promise for the Los Angeles Lakers ended with the pain of failing to even qualify for the play-in tournament. Tuesday’s 121-110 loss to the Phoenix Suns — coupled with a 116-97 win by the San Antonio Spurs over the Denver Nuggets — officially eliminated L.A. from play-in contention with three games remaining in the regular season. “Extremely disappointed,” said Lakers coach Frank Vogel. “Disappointed for our fan base. Disappointed for the Buss family, who gave us all this opportunity and we want to play our part in bringing success to Laker basketball and we fell short.”
