Exactly, Tokyo. I think those who expect Nishikori to win a major are insane. I also think those who think Raonic will win one are nearly as insane.
Nishikori has a better chance than Raonic in my opinion. Predicting any young player to win a GS before they reach that pinnacle may sound insane at the time, but I like his chances compared to the other young guys. If you look at the younger generation I'd put Kei right behind Del Potro in terms of favourites to win grand slams. I wouldn't be surprised at all if he won one or more.
