Beginning with the first day of the off-season, everyone hears about all the hard work players do during the summer to prepare for the next year. Spurs rookie (now no longer a rookie!) point guard Dujounte Murray earned well-deserved plaudits for showing up for his off-season workouts the day after the Spurs last game of the Western Conference Finals. Kawhi Leonard is famous for his off-season regimen, which has contributed to his marked improvement each year he has played.
In my day, Magic Johnson famously added something new each off-season, the junior sky hook one year, a three point shot the next, vastly improved free throw shooting another year.
