JK Simmons, Johnny Simmons and the Sopranos

JK Simmons was a really good actor and he found the part. Sterling K Brown has won awards, but hasn't had his Whiplash? There are dozens of actors like that. This is the rare, rare, rare case where JK Simmons and however old he was, you know, and the second half of his life got the part. Like does he just go the rest of his life? Or the kid in Whiplash like in the research. Johnny Simmons never happens for him.
