What are the 'trade rules". for the NFL concerning players, draft picks. I know you can trade players for players, picks for picks, player and picks for players and picks. Could the Cowboys trade for example-Marty B, a third, and say $10 miilion cash to Kansas City for a 2nd round pick? or Bobbie Carpenter and $5 million to St Louis for a 3rd and 4th round picks? i. e. What can a team trade or not trade??? Players? picks? cash? contacts? season tickets to a box?
