Need to let the players celebrate to some degree to enjoy their success and achievement. They battle for 60 minutes in a war night in and night out, and having a little 2 second triple low five is not showing any disrespect to anyone, its congratulating your teammate in a hard fought win. It's not " in your face" or over the top celebrations. It also can create some buzz among the teammates and get even more excitement going. Some celebrations are good.
