Lower Greed/Higher Loyalty
Greed and Loyalty can be found on the index under a player's personal page. The higher the loyalty, the more likely they will want to re-sign and remain with your team. Higher the greed, the more money they'll want when seeking a new deal. For 1.0 Million GM cash, you can add or subtract 10 points from either. You can only add or subtract once per player. This can only be done during the regular season.
