Wow. That's interesting. If you had not said that I almost would have taken poison on the fact that also defence is included in shooting.
I tried raising my shooting last season by raising the shooting on my defence players (their shooting really sucked) and I succeded. Question now is - how did I succeed in rasing my shooting.

Did I just play tricks with my own mind?
But even if defence players also attack their shooting is not taken in to account?
