Ok, so do you think there is no such thing as a talented guitar player, for example? Only skilled guitar players?
A person's ability to become more skilled is a talent, IMO. Everyone can improve their level of skill at basically anything. But how much and how quickly you can improve is a very individual thing.
Also, I'd argue that most of the things you listed as traits of physical talent are all skills that can be learned and developed. Not height, of course, but coordination, size, and body control are absolutely things that high level athletes train to improve. Larry Fitzgerald was a freak at making ridiculous one-handed catches. But that wasn't just pure talent oozing out of him, he trained incessantly to hone his abilities.
There definitely is such a thing as a talented guitar player (or any musician). "Talent" in that case might be having a good natural ear for pitch, a natural sense of rhythm, and good hand-eye coordination. All of those things get you a good start on an instrument. Those things don't automatically make you great. I also am certain that 95% of the greatest musicians in the world got as good as they did through 95% hard work and not due to "talent."
For reference, I'm a band director in Texas in one of the most successful music clusters in the country. I studied with, am friends with, and have former students who are some of the best in the country at their chosen instrument. I know how much "talent" they had when they first began, and most didn't have much more than anyone else in their class. What separated them was tireless work ethic and a desire to be great.
I'm not saying this to brag on myself (what a stupid thing to brag about), but to give reference for why I believe what I believe. I watch it in action every day. Everyone in the NFL has talent. Some may have more than others, but having more talent is the difference between being a Peyton Manning vs. a Matt Ryan, or a Calvin Johnson vs. a Derrick Mason. It makes a difference at the very top, but it sure as hell isn't going to stop you from succeeding if your work ethic is good enough.
Drew Brees is a great example. Talent level is average at best. Work ethic and intelligence is off the damned charts.
