Since he was traded from the Boston Celtics to the Cleveland Cavaliers in a blockbuster deal involving Kyrie Irving, Isaiah Thomas has been relatively quiet.

On Tuesday night, IT posted an Instagram video that included a lot of interesting moments, including footage of his clutch playoff performances, his rehab process and some recent shootarounds in his personal gym.

However, Thomas’ choice in background audio will have people talking. At the beginning of the video, the diminutive point guard provided a glimpse of himself talking to someone on the phone about the moment when he found out that he got traded.

“I call him back, he’s like, ‘How’s your life I.T.?’’ Thomas said as he was talking with a friend about his final conversation with Celtics president of basketball operations Danny Ainge. “I’m like I just got back home, I’m straight, and he’s like, ‘Well, I just traded you.’”

Check out the moment in the video below:

The caption that he provided was also telling.

"They say every man is defined by his reaction to any given situation. Well who would you want to define you? Someone else or yourself? Whatever you do, give your heart to it and stay strong"... THE MARATHON CONTINUES!!!#BookOfIsaiah2ComingSoon #ThatSLOWgrind #KeepDoubting #KillaSeason”

On a conference call to reporters after making the trade, Celtics president of basketball operations Danny Ainge said, “I will say this, I’m not going to share my conversation with Isaiah. As you can imagine, I’ll leave it to your own imaginations to realize how difficult that conversation might have been for me and Isaiah.”

He added, “Trading both guys was tough, but Isaiah had just an amazing season this year and entertained us all—the whole city of Boston. And everybody fell in love with him. He’s such an underdog because of his size and his heart and his spirit in which he plays. And it was very challenging to make this decision.”

Therefore, the footage that Thomas included was the first glimpse of what was said in the phone call with Ainge. Judging by his reaction, it seemed like he was surprised and hurt by the news. Since he had seemingly found a home in Boston and overcame a great deal of adversity after losing his younger sister to a tragic car accident right before the playoffs started, Thomas likely struggled to accept the news at first.

But, judging by the video and the caption that he included, it seems as though the 5’9” star is committed towards rebounding in a big way with his new team in Cleveland alongside LeBron James.
