Not simply in isolation.
Probably all of the last 17 Cup winners had an American player on their team, which does not prove that you need an American player on your team to win.

I would argue the control group is ALL teams. And it's an easier calculation:
1) What percentage of teams have a right-shooting C?
2) What percentage of cup winners do? (76%)
3) Is there a statistical difference?
