Fair Trade?
This trade is similar to Bane's, where a contending team 'overpays' for an elite role player/ subpar all-star player. Acquiring Murphy for Pistons, a 3nD player that can also shot create at a pretty high level, is a big help for a team that needs shooting and shot creation. Pelicans on the other hand though, get FOUR picks in exchange for him, selling him at a pretty high value.
