That's Seely Castle or Overlook Castle. It was built by EW Grove's son-in-law (same guy that built Grove Park Inn and Grove Arcade). UNCA held classes there back in the 50's. There's some interesting history (beyond Wikipedia) here
I can see us trying to deal Roberts, Daniels, Hairston, Taylor, Zeller, and Hawes. I'd be fine with trading Jefferson, but no one wants a broken down defensive liability. The problem is we don't have the assets to get anyone good in return for Zeller. Any chance Boston would deal us Hunter? They need bigs and we need shooters. Could be a good match.
