Jackie had dapper don written all over him.

Jackie Jr. was a little shitheel tough guy Italian into men's fashion. He had wise guy written all over him. Without the age difference, he could have slid right in when Jackie Sr. died, of course had Jackie Sr. allowed him into the life like some old timers did before (Carmine and Little Carmine). It had to be super frustrating for him. He wanted in so badly. Except for being too dumb, he was perfect for it. He could've made capo. He was born too late.
