Secondary positions

 Wouldn't it be great if some players had a secondary position, so long as they played 50 games at whatever other position the year before? It would help players avoid getting stacked at 1 or 2 positions and have players they can't utilize. For "utility" players that can be played all over (Ben Zobrist for example) you would just use the second position played most, to avoid certain players having crazy versatility. This is something I've wished the game had ever since I started playing, and most baseball games are aware of and at least consider.
