One of the most frustrating trips in the life of the current Celtics front office occurred shortly before the NBA draft, when Danny Ainge, Brad Stevens and assistant general manager Michael Zarren flew to Sacramento to work out Kansas forward Josh Jackson.

They landed, only to hear that Jackson cancelled the workout, prompting a steamed morning trip back to the airport. The Suns forward, in town for today’s game against the Celtics, pinned the problem on a disconnect with his agent, B.J. Armstrong.

“It was just miscommunication between me and my agent – couldn’t set up a workout,” he said. “The day they were supposed to come in I wasn’t aware and wasn’t prepared. So I’m not going to work out if I’m not prepared.”

The general perception was that Jackson didn’t want to play for the Celtics – as stocked as they were at the time with swing forwards like Jaylen Brown and Jae Crowder.

“I’m not threatened by anybody, ever. I welcome competition,” he said to that theory. As to the notion he didn't want to play for the Celtics, Jackson said, “No. Literally just miscommunication.”
