The largest contract that fits into the TPE is four years for approximately $43.87m, beginning at around $10.28m. Sign-and-trade contracts have to be at least three years in length. You can't sign another team's free agent and immediately trade him. You can, however, have a deal along the lines of Indiana signing and trading Stephenson to Minnesota, Love going to Boston, and Kevin Martin going to Indiana, with the Celtics presumably sending other stuff to both teams.
