Andy can do some things Rafa can't do.
For example Andy has some options.
He can finish at net. Rafa is too timid at the net.
Andy can go forward with confidence.
He was 13 for 17 at the net.
Very hard to beat Djokovic from the baseline. You have attack and go forward in order to give him different looks and also to bring him under some pressure.
I did notice that. Rafa never or rarely made his way to the net when he played Andy or Novak. You definitely can't beat Novak playing that far behind the baseline because Novak doesn't miss very often.
But, it was funny, when Rafa played Novak, Novak kept drop-shotting him and Rafa got to very few of them. He did later in the match, but by then it was too little, too late. Sunday, in the Rome final, he tried to do that to Andy and Andy started drop-shotting him right back. I don't think Novak liked that. It was funny.
