the original question was which where MOST important.
I clearly know that JR is an important skill for SF, but so is any other. In fact the perfect SF would have each skill as good as the others, and maybe JS a little higher. But that was not his question, on contrary, he stated he can not focus on all of them.
I am putting much attention into defense, more offensive managers could indeed swap the rebounding skill for the jump range in my preferences list...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
