Isaiah Thomas penned a letter for The Player's Tribune titled "This is for Boston," wherein he opens up about the recent trade and reveals where he was when he got the call from Celtics GM Danny Ainge. In discussing the trade to Cleveland, Isaiah says he doesn't agree with it but understands it was Boston's right to trade him.

The new Cavs point guard writes,

"I don't agree with it, just personally, and I don't think the Boston Celtics got better by making this trade. But that's not my job. That's Danny's. And it's a tough job, and he's been really good at it. But at the end of the day, these deals just come down to one thing: business. So it's no hard feelings on that end. I'm a grown man, and I know what I got into when I joined this league—and so far it's been more blessings than curses. I'm not sitting here, writing this, because I feel I was wronged. I wasn't wronged. It was Boston's right to trade me."

The 28-year old All-Star point guard is still rehabbing from a hip injury but he has remained confident that he'll be back and he'll be the same player. However, reports have recently surfaced suggesting Thomas' injury could keep him off the court for months, possibly as long as the NBA All-Star break in February. 

In addition to the lengthy letter to Boston, Isaiah Thomas also released a video on his instagram account which outlines the next chapter of "The Book Of Isaiah" as he prepares to help the Cavs reach another NBA Finals.
