Well if you can land Niko or Rudy Gay to play the 4 then you should be fine with a lower usage guard. Exum is over 20 as well.
The argument that we need Ricky because he has a higher usage and it’s valuable is not great... considering that the usage of the possessions is not great.
I just think when we describe a guard that is good at defense, can use a fair amount of possessions, is a little bigger than pg size, and is a good shooter you are describing Gary Harris on the low end and Brad Beal on the high end... maybe Brogdon if you squint a little but he’s not as versatile on defense as I’d like. I think it might be easier to get the shooting, defense and size and get usage somewhere else.
