Loyalty is a dying art in professional sports. What used to be a game about who drafted the best players and applied the best system is now about who can buy the All-Stars. Gone are the days of all the greats who stuck it out with their team from start to finish.
Dirk Nowitzki is no long considered the norm and is now an outlier among NBA stars. Players like LeBron James and Kevin Durant represent the best this league has to offer. They are not loyal to a team but are willing to go where they need to in order to win a title, unable to do it on their own.
