If RG gets away this will end up being the most trying and most difficult for him.
I am hoping we are able to bag RG somehow and then return a lot stronger physically in 2016.
Or, he could go on a tear. I don't think Rafa would sulk after a loss, even at RG. I think he would put the hard hat on to make up for lost time.
He shouldn't be obligated to win RG every year. it's been a phenomenal run, but it wouldn't bother me too much. Maybe a little initially, but I'd get over it, especially if he won the Open. It could happen.
