I go oppo on the Stan thoughts. Read many articles where he admitted he was having a tough time with finding much consistency and admitting maybe his effort level has been trash at times since winning the Slam. I dont think he was resting.
My thoughts on Djokovic-Cilic is that it could go like Fed-Raonic. Cilic may be nervy or rusty to start. If Djokovic lets him get comfortable though, it could be tight. I tend to think he won't, but I am wrong plenty obviously.
