Hall of Fame
I don't see Cilic winning any more majors. Just like Delpo.FO - Nadal
Wimbledon - Djokovic
Canada - Raonic
Cincinnati - Federer
US Open - Cilic
Shanghai - Kyrgios
Paris - Djokovic
WTF - Federer
I think Federer is going to win 1-2 more big titles in 2017 but not a Slam (a big hitter will knock him out at Wimbledon). Went with the obvious Cincinnati and WTF.
With Federer back in action, Djokovic getting into form again and the new generation finally coming to play I don't think Nadal is going to win anything outside of clay this year so only went with the FO for him.
Djokovic is getting some of his mojo back, I feel he'll get a good draw at Wimbledon and win there one last time. He'll be in contention in most of the remainin tournaments but he'll only win one more big title (going with Paris). So Wimbledon and Paris MS it is for him.
Raonic - people are writing him off too soon, I think. He's a solid top 10 player and with the home crowd behind him I think he can win Canada this year.
Cilic - he's had a very good clay court season and win the right surface (hard or grass) he could be really dangerous if he fires on all cylinders. A repeat of 2014 and he's the 2017 US Open champion.
Kyrgios - with it being late in the season and a fast hard court - Kyrgios could win a MS title himself this year. Shanghai for him.
