It was in his time as a member of the Boston Celtics that Isaiah Thomas asserted himself as one of the premiere point guards in the game.
Standing at just 5-foot-9, Thomas has had to repeatedly prove himself in this big man's league time and time again.
This go-round, you'd think he'd turned the corner. Though the Celtics became Thomas' third team in his first five seasons, it finally looked as though he'd found himself a home.
He averaged career bests in points and field goal percentage in what turned out to be his final season as a Celtic, and even gave the C's a 53-point performance in the playoffs shortly after losing his sister.
Thomas played his heart out for the Celtics.
And what does Thomas get in return for having the best season of his career, giving his all to the team, and leading the Celtics to a first place finish in the Eastern Conference?
In aftermath of the ordeal, whether or not Thomas has actually wound up on a better roster is beside the point. The fact of the matter is, he must certainly feel like there was no loyalty shown on behalf of the organization, but more specifically, Celtics GM Danny Ainge.
Thomas has since said he will still talk to others inside of the organization, but not his former GM, and Ainge had a particularly interesting response to that sentiment.

It sounds as though Ainge understands that he did Thomas wrong, but that's the business of it all.
To Thomas, the fact that business came before loyalty is likely what has wrecked him to his core.
In the end, if these two can't mend the relationship, it'll be easy to see why. You can't take it personal, but it's hard not to given all that Isaiah did for the franchise in just two short seasons.
