What happened: Charlotte and Washington have each gone without a direct trade with Toronto. Orlando and Indiana have likewise never made a deal with each other.
Why it matters: Toronto is the central outlier among the five clubs, appearing in two separate pairings. A first deal in any matchup would erase one of the NBA’s remaining transaction oddities.
By the numbers: Three pairings involve five franchises. Toronto appears twice; Charlotte, Washington, Orlando and Indiana each appear once.
What to watch: Future trades between Charlotte-Toronto, Toronto-Washington or Orlando-Indiana would shorten the group.
