I'm not putting too much stock into these rumors. I think a these " sources" are ridiculous.
I think what you see is what you get, maybe a small tweak here or there. I don't think we'll see any big moves for the rest of the summer. The truth is I'd rather the C's continue to stay in a holding pattern and just try to add through FA again. They'll have the space and still have the assets to make a trade.
IT, Bradley, Crowder, Olynyk/Johnson, Horford is a solid starting 5, a top 3 team in the East. Stay the course. You never know how it will play out.
