The NBA's annual trade deadline is set for 3 p.m. ET on Thursday. We have already seen Indiana Pacers big man Domantas Sabonis sent to the Sacramento Kings and Portland Trail Blazers guard CJ McCollum dealt to the New Orleans Pelicans. Negotiations on a swap of Brooklyn Nets star James Harden and Philadelphia 76ers counterpart Ben Simmons could gain momentum at any moment. What better way to pass the time between than to remember the 33 trades in the league's 75-year history that directly swung championships.
