I'm not a coach. I never have been and never will be. But here is my perspective from the outside looking in. If you're willing to chest bump after a sack or a touchdown, you should probably be willing to do the same after getting an A on a test. An education, whether college or self, will take 99.9% of all high school athletes further than their 40 time. Life success is long term, whereas football success is not. Being the star and captain of your football team is a fantastic accomplishment, but being a successful CEO of your own life is an even better one.
Chest bump all you want, show swagger, and have fun. But do the same in the classroom (players) and with your family (coaches) or it's all for naught.
