I doubt Lillard will be playing much SG in the regular season. I bet this is just a way to jack his minutes without forcing him to run the team the whole time.
I understand it's preseason, and I understand what preseason entails, but I'm hoping as we get closer to the regular season that he actually lets the first team get some time together. They don't have much chemistry yet.
I'm taking the long-view with this season. It's all going to take some time ... maybe a whole lotta time.
