A difference making guard would go a lonnnnggg way for our club. Main questions:
-Will Johnson be able to get that guy / guys?
-Will Johnson be able to use them appropriately to get the most out of them?
I really can't answer the second question as I don't feel strongly enough even to speculate.
As to the first question, one's answer depends upon one's definition of a "difference maker." My definition would be one who could make "a difference" Doesn't have to be "a huge difference." For example, Johnson would have virtually no chance of getting a difference maker like Marcus Carr and probably not even one like Payton Willis. If he could find someone like a better shooting version of Luke Loewe I think that person could make a significant difference without being a star. I think Cooper could be better next season (on a per minute basis) if he doesn't play as many minutes and another guard helps to shoulder the load.
