You people relise that Djokovic and Murray are only 3 years older than Raonic? And Delpo only 2 years? Raonic is allmost allways put in the group with Tomic, but the difference between them is as big as between Delpo and Raonic. Novak, Andy and Juan will be there long enough to own him until he gets past his peak and starts getting owned by the younger guys. He can maybe be a 1-slam-wonder, 2 slams MAX, but he has to get on a much higher level and I don't see how bcs he doesn't have good enough return game and is not improving it to avoid close sets and tbs, and when you play as much tight matches, you are bound to lose 1 in a few (7?)...
People talk as if Raonic is 18/19. He is nearly 22, and yes he probably does still have his best years ahead of him, but his best achievements so far are slam 4th rounds and masters quarters. Nothing that special really.
