The Ricketts, Reinsdorf, the Steinbrenner brothers, and several other owners expect this round to focus on centralized revenue sharing from media markets and better cost certainty for the teams. They are going to hammer the collapse of the RSNs as a means to introduce a harder cap, but not a true salary cap, as they don't want to open their books to the players. They are going to talk about the disparity in payroll as if it's the players' fault.
If they get what they want, players the Cubs like to target will see their market value dry up. It's already happening to some extent, and it's only going to get worse.
The strategy is to "keep the books clean" so they can target the same types of players and pay them less than they would under the pre-CBA agreement. It obviously does not affect the players currently under contract. But someone like Ian Happ is going to see his earning potential diminished in FA (if they get what they want).
