The Importance of Speed in a Steal of Home

Cunya is a savvy base runner. He has speed to really make the savviness sing. Even his his still of home in that inning relied on inattention on the part of the catcher and pitcher. It wasn't like they knew he was going and they still just couldn't catch him because it was so fast. So I don't know which of his tools or skills is the most impressive at this point.
