One coach who won’t be participating in the offseason NBA coaching carousel is the Bulls’ Tom Thibodeau.

Early Sunday afternoon, there were whispers that if the Boston Celtics trade coach Doc Rivers in a package to the Los Angeles Clippers, Thibodeau would be on the radar as a possible replacement. But an NBA source indicated Sunday evening that the Celtics would not pursue Thibodeau because they know the Bulls would not grant permission to speak to the former Celtics associate head coach.

“He’s loved in Boston, but he’s loved a little more by Chicago,’’ the source said.

The Bulls just gave him a nice raise when he signed a four-year contract extension that will pay him $17.5 over the next four seasons.

Still, it will be interesting to watch when Thibodeau’s deal gets closer to running out. He was born and raised in Connecticut and has strong ties in New England. As this offseason has shown the NBA coaching world, anything is possible.

◆ Thibodeau likes bringing in players he has history with, but that won’t be the case with former backup guard C.J. Watson, who opted out of his deal with the Brooklyn Nets this week and will be a free agent. There’s too much stagnant water under that bridge.

◆ Of the four previous titles won by the San Antonio Spurs, only one went seven games. That came in 2005 against the Detroit Pistons, when the Spurs had home-court advantage.
