That is as much about who he is as how he plays.
Bosa was born to be this guy, bred to be this guy. He is represented by the world’s largest agency. He has a nonchalant charisma that belies yet complements his ferocious playing style.
His is an extremely engaging kind of condescension – like you know that he knows that you know you aren’t as cool as him, and it’s OK with everyone.
He speaks in a soft monotone. The casting call for his role in the “Joey Bosa Story” would be part Jeff Spicoli, part John Rambo.
