Mark Randall was not loyal to one team. 
The statement Mark Randall was not loyal to one team' is definitely correct because the context says he played "for the Chicago Bulls, Minnesota Timberwolves, Detroit Pistons, and Denver Nuggets". The fact that he played for four different teams over his career means he was not loyal to one team. I think the system found this difficult because it didn't understand the meaning of the word 'loyal'and how it applies to him.
