One of the characteristics of most good sports shots is that the actual player activity is isolated from the background and contained within the shot. Thus many sports shooters use fast lenses and close-to-wide-open apertures to get both razor sharpness and isolation.
Additionally, good shots really focus, no pun intended, on the important stuff and the unimportant stuff is left off or cropped out.
Lastly, good shots generally show the interaction that sport implies directly.
In your picture, there is way too much, the back wall is sort-of in focus, we can see the face of one guy and not the other, the interesting stance is hidden and we see only a very indistinct blur of the man being thrown and we don't see much if any any of the interaction.
If you were 90 degrees around the mat to catch the stance, the faces, the inter-locking hands, the stance, all of that would have made a better picture
But you have the opportunity to shoot more.
