Key points:
1. Ericsson only published averages. Nobody else has seen the raw data. He didn't even give standard deviation or error bars.
2. "Talented" people get more positive feedback and so practice more.
3. There are so many observable phenotypal inputs and as yet unobserved phenotypal inputs into sports performance that pinning it to a single variable (hours of deliberate practice) is nuts.
My sport is Olympic weightlifting.
Some people will never be Olympic champions, no matter how hard they train. Factors affecting performance include:
* Height.
* Relative anthropometry: long legs are worse than short legs. Long torsos are better than short torsos. Long arms are better for the snatch, worse for the clean and jerk.
* Fast-twitch fibre / slow-twitch fibre ratios.
* Tendon insertion geometry.
* Muscle-belly / tendon ratio.
* Pelvic geometry.
* Soft tissue robustness.
* Natural hormonal environment: ratios, natural circulating testosterone and DHT, amounts of SBHG.
* Placement and density of testosterone receptors in muscle tissue.
* Myostatin production.
These are basic physiological qualities that cannot be changed by any amount of training. While the statistics show that lifters who start younger out-perform lifters who start later (because it's a high-skill sport and childhood neuroplasticity is much higher), the historically and currently dominant countries in weightlifting have gotten there by simply having much larger pools of candidates to find genetic outliers in.

a) Doesn't make the 10,000-hour figure a rule as both Epstein and Repanich would have us believe.
b) Fully concedes that there are myriads of other factors that have an effect on how one reaches "expert status".
I'm also not sure how Epstein can claim that the chess master study is somehow disanalogous with the athlete one. An expert athlete might have some physical advantage over your "average Joe": speed, lean muscle, endurance, height, etc., etc. Similarly, one can say that an expert chess player may have some neurophysiological advantage over the "average Joe": better-formed synaptic pathways, higher attention span, etc., etc. I don't think there's any difference between an expert chess master or an NFL quarterback.
Both might have some genetic advantage; both have trained extensively. The idea behind Gladwell's figure is not that you can practice X for 10,000 hours and then you will instantly be an expert at it, but merely that after 10,000 hours (of deliberate practice plus a number of contingencies) you can expect to be somewhere in the realm of expertness.
There are plenty of other studies that favor this hypothesis; in particular, some very interesting double-blind identical twin studies[1].
Outside of extreme cases (e.g. I am 4'11'' and want to play in the NBA; I have an IQ of 90 and want to be an astronaut), I think Gladwell is right on the money: practice is more important than talent.

This generalizes to other activities easily. The best practice I've found comes from complete effort in game/competition like environments.

I played golf at a pretty high level throughout high school and college. I practiced and played golf on most days for 8 straight years. I'm sure I reached 10k hours. Currently, I don't have almost any time to practice and play golf. I haven't practiced or played regularly in at least 6 years. Yet, playing once every 2 months or so I'm still able to shoot at or near par most of the time. I suspect this has more to do with the 10k hours of practice than my natural abilities. Not really any way to prove that, but I suspect a similarly athletic person who hasn't put in that practice wouldn't generally shoot par playing 6 times a year.

Genetic advantages are interesting.

Another way athletes become great though, in all seriousness, is they hack their bodies with PEDs. Seems to me like sports these days are flooded with it.
