Nadal was out longer and was able to include more of his points. Andy dropped out of several events after entering so his rise will be slower. I will be patient and hope the media are too.
Very true. While Nadal was out for longer in one go than Andy, Andy's lighter schedule, then withdrawing from Rome and RG prior to Wimbledon, means that Andy was dropping points compared with his potential, long before he announced his surgery. He has the opportunity to gain them this year if he feels he's sufficiently recovered. There's a fair chance that Andy might stick to a lighter schedule until he's certain he's fully recovered, and got full strength back.
I'd also argue that once Andy is fully recovered, he'll be able to invest time and effort in working on his shots and general tactics that may have been put on the back burner while he was struggling physically. People have often wondered why he didn't work more on his 2nd serve, but I wonder if that kind of extra practice wasn't worth it when he was managing the pain.
