While the Los Angeles Clippers will attempt to re-sign Blake Griffin, the Boston Celtics are considered a primary threat to sign him away.

"Boston is really the danger for Blake Griffin," said Wojnarowski. "I think Boston's two primary free agent targets, right now, are Gordon Hayward and Blake Griffin. Now they're not going to get both of them, but they're both players that would potentially have interest there. I think Boston looks at in different ways with their future."

Griffin also is said to have noticed the way Boston embraced Paul Pierce during his final visit.

Griffin has been limited to 67 games, 35 games and 61 games over the past three seasons after he finished third in MVP voting in 2014.

Griffin has never been a free agent before in his career.
