RE: Don't Mess With The Milos
Good stuff, Broken. It supports my view that Raonic's absolute ceiling is of a "near-elite" (#6-10ish) player, and maybe not even that, at least on a consistent basis. He hasn't quite gotten there - but his recent victories over Del Potro and Berdych are promising (Juan Martin's injury aside). But to be in the true elite, you simply must have a more diverse game and be able to adapt.
The Karlovic and Isner comparisons are interesting - although, in the end, results should mean something. Ivo reached #14, but not until his late 20s. Milos is already 5-6 years ahead of him in terms of developmental timeline. Ultimately Ivo isn't a good comparison, except as a vaguely similar player. Milos is just a better all-around player.
Isner is a bit closer, although Milos is also quite a bit ahead of the big American developmentally. John started a rapid ascent in the rankings at age 24, first reaching the top 20 about a month before turning 25. He hung out in the #18-35 range for a couple years before rising last year to as high as #9. He's been a fixture in the top 20 for about two years now and hung out in the #9-11 range for about eight months last year before falling back a bit again.
Milos made a big jump into the #20-40 range at age 20, and then breached the top 20 for good at age 21, a few months before turning 22 last year. So he's only been in the top 20 for a little over a year and has gradually edged his way up.
If the elite of the game are people that, as Broken said, "live in the top 5," and the near-elite live in the top 10, there's a third tier that live in the top 20 - and that's John Isner, whereas a 4th tier player is more like a top 40-50 player (Karlovic during his prime). What I think remains to be seen about Raonic is if he's going to be a 2nd or 3rd tier player, as the 1st tier seems unlikely. Given his young age, I wouldn't bet against him being a legit 2nd tier player. In fact, I fully expect him to be a fixture in the top 10 for a few years to come.
Ultimately the proof is in the pudding. His game may not be pretty, but overall he's quite effective - more effective (thus far) than the prettier Grigor Dimitrov. Milos has been a bit of a punching bag of late, especially after the Canada Masters, but he's still the #11 player in the world and the highest ranked player born in the 90s. I'm guessing that at some point next year, Jerzy Janowicz and perhaps Dimitrov and just maybe Bernard Tomic will be right there with him, but for now he's the most successful of the Young Guns.
