There is no way Toronto would agree to this. Artest for Ford is a stretch, let alone saddling them with KT. This just doesn't fit what Colangelo has been building at all.
I disagree, Ron from TJ is an upgrade, ESPECIALLY when you consider the spinal stenosis he's dealing with. Also, you're not looking at the BIG picture for Tor. Calderon is an FA, he'll want something in the 7-10 million dollar range IMO. Are you gonna pay 15 million for your PG tandem if you're BC? You can keep Calderon more easily in this deal because you shift TJ's salary to your area of need SF and upgrade it significantly to Artest. That's smart management there.
