Even after roughly $1.5 billion in contracts were finalized during the first two weeks of free agency, there is still plenty of shopping for NBA teams to do over the coming weeks. Most of it will be for bargains. The biggest deals of the NBA summer — like Chris Paul, Paul George and LeBron James getting contracts that will pay them a combined $450 million over the next four years — almost certainly are done. A blockbuster trade involving San Antonio's Kawhi Leonard still can happen, and at some point, Carmelo Anthony's exit from Oklahoma City, mostly likely to Houston, will be completed.
