Good thing for him is he got that first tour title out of the way quickly so he's already got a goal that could have been a real annoyance done. Next goal would be a bigger tournament, which would be a masters 1000. That will be tough as he is right now, but by next year I think he'll be ready to win one of those and then start seriously challenging for 2nd week in GS's.

Depends on how much he can improve. I don't know if people think his serve is some kind of super weapon? Like the top20 doesn't already have many guys at his height that can serve at high level but with way greater ground game. If Raonic want to get into the top10 and get a seeding that will give him a better shot to go deep in slams he must get his RoS and baseline game to top10 level. Right now there is nothing about Raonic that says future slam winner. But as we know it can change fast. It is also very rare that someone just walks in and grabs a slam in his first deep run so likely we will see him in a QF/SF/F before it's time to seriously consider him going all the way.
