"I (think) it would be a footnote, and it would be something that's in history that maybe my grandkids can talk about," added Bickerstaff, who hasn't said whether D'Antoni will keep him around. "It's all fun, and that's what life is about. Don't take yourself too seriously, and enjoy the ride."
Goran Dragic scored 22 points for the Suns, who have lost three of four.
Luis Scola scored 18 points, while Michael Beasley added 14 points and a career-high nine assists. The game is Phoenix's only road contest in a six-game stretch through Thanksgiving, but the Suns must rush home to face defending champion Miami on Saturday night.
"That team is in another area as to where we are and where we're trying to get to," Gentry said. "They've got much bigger fish to fry, and we've got to get ourselves to the point where we become significant again. And the only way to do that is to be consistent."
Steve Nash missed his seventh straight game for the Lakers with a small fracture in his left leg, keeping him out of his first potential matchup with the franchise with which he spent the past eight seasons, winning two NBA MVP awards and reaching two Western Conference finals with D'Antoni on the bench.
During the third quarter, the Lakers announced Nash will miss at least another week before getting re-examined next weekend. The Lakers are in the midst of a heavy slate of games, meaning the point guard is likely to miss 12 straight games before the Lakers' next projection on his return.
The results of D'Antoni's arrival seemed obvious from the opening quarter, when the Lakers scored 35 points and ran the court with an urgency they haven't consistently shown in years. Both teams traded significant runs in the second quarter, with the Lakers taking a 62-57 lead at halftime after closing with a 12-2 surge.
"We gave ourselves a chance, but we had a lot of unforced turnovers," said Jermaine O'Neal, who scored 12 points. "They capitalized on the turnovers that we had in that one spurt in the third, and they scored in transition. That was the difference-maker."
NOTES: The Suns have trailed by double digits in nine of their 10 games this season. ... Eddie Murphy, Andy Garcia, Los Angeles Kings forwards Jarret Stoll and Trevor Lewis, and "2 Broke Girls" stars Kat Dennings and Beth Behrs attended the game.
