What I mean is conceptual thoughts are not necessarily connected to physical ability, for example you may be able to calculate the necessary trajectory of a ball for example, but actually making such a pitch or hitting it or something is another story. You may know the math very well but simply suck at playing ball, and what we're talking about is how to play ball.
Just an interesting point on this particular comment, which is probably off topic. It has been found that conceptual thought can enhance actual physical performance. If a person mentally practices a certain physical action, their performance is improved when they carry out the physical motion.
For instance, I've had difficulty in relaxing and properly riding my horse when he canters. When I'm physically in the saddle, I tense up and simply can't relax sufficiently to ride properly. However, if I "practice" the proper riding technique in my mind beforehand, I find that I can easily transfer my mental image and practice over to the physical occurrence of the event.
This has also proved true for many others.
