Yeah but you're then motivated by FEAR - which to me is the wrong motivation IMO.
We should be motivated by LOVE. In this case, hopefully Burke is motivate to win/improve because of his love for his teammates, love for his coaches, love for his family and ultimately love for the Utah Jazz franchise.
I would rather he wants to do that, than motivated by the fact that there is another guy "gunning" for your job.
Big difference.
Don't forget: Fear leads to Anger, Anger leads to Hate, Hate leads to SUFFERING.
