Lack of spacing isn't only the fault of the frontcourt though---it also hurts having your PG be a terrible shooter. Teams are cheating off our bigs and KC (on the perimeter) and loading up on the two poor suckers that shoot 3's (Emery/Fischer). This is primarily why IMO Rose has started experimenting with Hartsock in the starting lineup so we have a 3rd shooter on the floor. Dave Rose's offense HAS to have a minimum of 3 shooters at all times on the floor---otherwise his weave will suck and his frontcourt will suck too because of spacing.
This isn't a knock on KC---he's a great player---it is just unfortunate that our personnel doesn't mesh well especially with the schemes they run. We don't have the RIGHT personnel to be a really good team despite having some decent players.
