To be clear, I think the odds of Rafa winning in 3 easy sets are greater than the odds of Stan winning.
I'm just saying that we've seen Stan playing in a zone before like in the 2015 French Open Final. When Stan gets hot, it is beautiful to watch and scare for the opponent, who gets overpowered. So I think it DOES depend somewhat on Stan's form. If he gets hot, he can make it a match against Rafa and even win. But yeah, I would expect Rafa to take it tomorrow under most circumstances.
