Last week, the Cleveland Cavaliers let go GM Chris Grant, and Sunday, the Detroit Pistons fired coach Maurice Cheeks and … presto! The Cavs promptly ran off three wins in a row and the Pistons pounced on the “model franchise,” the rodeo-tripping San Antonio Spurs. Wow, what turn-arounds! But … I have seen this movie many times, folks. Before the players revert back to who they really are, they’ll want to demonstrate THEY are not to blame. Rarely, though, will a team continue winning and thus prove the change was unwarranted. ####
