The Stamkos slapshot is a work of art, crafted over years and years of repetition. From firing puck after puck into a rubber mat outside a mall as a kid, to having an assistant coach feed him puck after puck in an NHL arena, Stamkos has literally done this thousands of time.
When a player can achieve success even though everyone on the ice or field knows what he’s going to do, it’s truly amazing. Think of Mariano Rivera being a dominant closer even though he threw the same pitch over and over. It’s the same with Kareem Abdul-Jabbar's skyhook.
