Perhaps thats why JC is named the starter, and Guyton has been tendered an offer.
Harpring then makes sense at the three because Rose would play a lot of '2' presumably with Eddie on the floor and then who comes in at three?
Jay Will wasn't a great basketball player until he had a season under his belt. The staff may be feeling the same for his rookie campaign.
It also gives us a chance to let JC really strut his stuff so we can max out what we get for him.
