I can't see any of the mentioned players as world number one. Andy is so weak on clay and there's so much of it on the calendar that he'd probably have to win two of the other three slams just to compensate for the landslide of points he'll lose to other top players in that time frame. Even when he held US Open and Wimbledon championships at once he was nowhere near reaching the top spot, albeit that was partially down to injury. I'd give him as much chance as any others mentioned here but after this year, I don't know.
Nishikori is probably the most logical choice out of the next/lost generation, but for some reason I just don't see it in him either. Maybe it's the injuries. Also, for all the good things he's done this year, he'll start his 2015 campaign as a 25 year old and he's yet to win even a Masters 1000 title.
Dimitrov seems to make spurts of progress then fade for a couple of months, he's a streaky one so it's not out of the question that he might have one massive "up" year and make it to the top spot, I wouldn't be all that surprised. I'm going off Grigor for some reason though.
Raonic is the most solid of the "next-gen" trio I think, but with lower peaks than Kei or Dim, he's fairly consistent across all surfaces and tends to at least meet his seeding in most tournaments. Again though, I don't think I see the real "numero uno" quality in him, he's a slightly better version of Berdych in my opinion.
Somebody has to be the next new number one though, and it's not certain that Nole, Roger and Rafa will hold the top spot long enough to keep these 4 guys off it before the Kyrgios/Coric generation overtakes the lot of them. Obviously I hope Andy gets it, and I think he has the best chance of these four, depending on whether his 2014 is the exception or the rule to the remainder of his career.
Therefore, I'm voting no in the poll!
