My instincts tell me that Ralph will mostly focus all his energy on winning RG for as many years as he can(he doesn't STILL have a challenger there apart from Djokovic 2.0 even after 8 years of winning,Incredible.) He might sneak in a Wimby somewhere and an AO if push comes to shove and basically overhaul Fed's slam record,that's probably his strategy.
The chase ain't over till Ralph officially pulls the plug on his career.He's not gonna just kill his dream when's he's still within striking distance.
If there's one thing I've learnt about Ralph is that he's the biggest opportunist the ATP may have ever had. Too bad some people can't see it.
