If you want to improve the team and be competitive, you might sign Ryan O'Hearn or Nathaniel Lowe.
If you want to keep your costs down, sign Christopher Morel. It might be dead money after a year, but you've kept your costs below what you get from MLB. and improved your profit that way, or you improve the value of the player, which gives you a trading chip further along the line.
It is not about being the best team possible, it is about making as much money as possible.
