All I can comment on this topic is that we were having this exact same conversation last season. X was graduating, Scott, Ali, and Thornton hadn't signed, and a lot of people thought this season would be a rebuilding year. I remember people commenting that Groce would maybe try to leave for a better job while he had the chance.
Now people are commenting that this season is the great team that is going to fall off. Just goes to show that you never know what the future will bring.
