It probably also helps too that you can go back and see that Fred truly does play the hot hand. So coming off the bench doesn't automatically assume you're getting less than starters minutes. How many times did JLaw play a ton of minutes off the bench late or how many times did KT ride the bench on his off nights for extended periods of time.
I think Fred does a really good job of not getting caught up in how many minutes a guy has or hasn't played and rides who is hot more often than not.
