Bird's infamous for his "
coaches get stale after 3 years philosophy."
Although he hasn't held firm to that over the years (Carisle got 4 years, Vogel got 5 1/2), he supposedly used that logic when he fired Vogel (technically he just didn't renew Vogel's contract).
While I can 100% picture Bird saying what Thomas is saying he said, I just can't picture it in the context Thomas is giving.
"I just like Rick better than I like you." I can actually see Bird saying this in a trash talking, friendly banter sort of way.
But I think Thomas is playing up the praise Bird gave him, while also ignoring the fact that Bird probably emphasized the team needed a new voice, and that Bird himself just stepped down after 3 years as coach.
