No, not really. If Froome was the one to have that all-time talent, then his circuitous route to the top and transition from also-ran to dominator is not the path people would expect from somebody having that talent naturally. Peter Sagan, for example, is a good example of a route to the top people might have expected from somebody with an all-time-great natural talent level. I don't know whether Sagan is doping or not, and I do have my suspicions of him, but he arrived on the World Tour aged 19, and in his very first stage race appeared in a queen stage breakaway with Evans, Valverde and LLS. Sure, it was only the Tour Down Under, but he immediately put down a marker that said "this guy is outrageously talented". Or, if you want to insist on GT contenders since that's the kind of rider Froome is, try Nairo Quintana. His rise has been very fast, but he was pegged as a potential world beater from the word go. Froome, to put it mildly, wasn't. So why would it be him that was the first to show that level clean and not, say, Alejandro Valverde, who destroyed every race he entered as a kid and went undefeated for three years from ages 11 to 14? I mean, Valverde's rise is the kind of thing we might expect, it's just that we know somewhere along the line - we don't know where - he started doping, so where his actual talent level is can be debated.
Even with Froome's unusual path into cycling, which grants him a great deal more leeway than others in terms of allowing for a slower and/or later progression, if he really was capable of putting out these performance levels we'd have had more to point to than lasting slightly longer than Johan van Summeren and finishing 9 minutes down in the TDF queen stage, and a top 20 in the TT a couple of days later, over three years before his transformation. If he is the guy who can best the péloton's best doped times clean, surely he should be beating guys like Haijun Ma, who is the same age, against the clock in the B Games? Surely he should have been able to out-TT guys like Velits and Daniel Spence in the mountain TT at the Giro del Capo, since he's got the natural talent as both a TT rider and a climber despite never going in a wind tunnel, to match people who spank those guys to all parts? Surely he shouldn't be losing 11km hillclimb races by 3 minutes, and being beaten by guys like Andrey Medyannikov? It speaks volumes that in 2009, when Team Sky were being first talked of in the press and the first media bluster was being presented, and they talked of a British Tour winner in 5 years, they were scoffed at. Who was going to be a British Tour winner, they said? Wiggins was, at that time, a one-hit wonder, and 2010 would have seemed to have indicated he may not be the guy going forward. Geraint Thomas was heavily hyped, Peter Kennaugh even more so, after his impressive Girobio, indicating a British rider who could legitimately climb. Froome was barely mentioned even as a footnote. And this was before his results turned south due to bilharzia, so that justification can't really be used here either.
Froome showed in his Konica Minolta and Barloworld days enough talent to say he was worth keeping an eye on. As I've said before, I thought he could develop into a pretty useful pro level mountain domestique or GC hand for a smaller race. I had a guy like Chris Anker Sørensen in mind as to the kind of level I expected of him. Some people may have expected more, but I simply do not believe anybody who claims they looked at Chris Froome in 2007-9 and said "that is the guy who will be the first to topple the best doped times of the EPO generation clean". They're liars, each and every one of them. Even those like blackcat who say they thought Froome could legitimately be a GT-winning talent acknowledge that he's probably doping, but take the stance that all of them at the business end are doping and Froome is talented enough to be there at the head of the field on merit.
