well its not actually him. its someone playing him, and thats why they never showed his face
It's the great Larry David playing him, btw. But yea, massive loss for any Yankee fan. The man changed baseball and professional sports in America. Steibrenner was a true American legend, as big as Babe Ruth, Branch Rickey, or anyone else to play or have anything to do with baseball.
Steinbrenner didn't just represent the Yankees, he represented New York. Since the Yankees won their first championship with him in 1977, he has owned New York City and they didn't just call him "The Boss" for no reason.
