Does it make it clearer that it was intended as a joke if I pointed out that Georges Niang is an Iowa State player who will be a sophomore next season?
Niang joked that Hoiberg turned down the Celtics job because he had had enough of Boston just from dealing with Niang, who is from Methuan, MA.
So, the joke is a) the ridiculous idea that Hoiberg would turn down the Celtics job and b) that Niang is obnoxious enough to make his coach want nothing to do with Boston.
