"It was a good meeting," said Kelly. "Everybody in the room was frustrated with our season."
The Lakers finished 21-61, leaving them with their worst winning percentage in franchise history, at .256.
"It's a lot more losses than I've experienced in my life," said Kelly, who played much of the season out of position at small forward.
"I was sacrificing a little bit," said Kelly. "[It's] not my natural position."
The Lakers were overloaded at power forward and center but woefully thin at small forward.
"Everybody knows and the [Lakers] knew all along that it wasn't best for me individually but it's what we needed," he said.
"When I got the opportunity to play the four (power forward), I did some pretty good things I think, both offensively and defensively," said Kelly, who averaged 5.2 assists over five games in April before an injury to Wesley Johnson moved him back to small forward.
"I'm going to train to be a four, a stretch four," said Kelly of his summer plans. "I've got to be a better shooter, a more consistent shooter from range."
After battling through hamstring injuries at the start of the season, Kelly played 52 games with 34 starts, averaging 9.7 points and 2.7 assists, shooting 33.7% from the field and 33.6% from three-point range.
Kelly was married last summer. Soon he'll be a father to a baby boy. The Duke product is into the final year of his contract with the Lakers next season at $1.7 million.
Kelly tried to take something positive out of the Lakers' season.
"I grew as a player," he said. "I'm probably not a starting three in the NBA, but the more positions you can play, even spot minutes, the more valuable you are."
