IMO, everyone should be an agnostic on this issue. Once I spend my money, I don't care how they divvy it up. But a couple of modest proposals:
The owners and players should agree on what constitutes a fair distribution of revenue. If they agree on 50/50, for example, and define what the sources of revenue are, most of the work is done.
I like a floor and cap. Consolidate all TV revenue under the auspices of the league office and distribute that evenly. That will level the floor. Local teams keep all local money, hopefully providing motivation to provide the best reasonable product for the fans.
The numbers for the floor/cap is less important, since the players still get their 50%. But I'd like to see a three-year rolling average for the floor. If the floor was say $120M, and a team is re-building, this allows them to spend $80M, $80M, and then $200M.
Reducing the season to 154 and expanding the playoffs are a no-brainer.
I think most fans, on both sides, agree that more should be done on the lower end. I've mentioned this before, but if a player is promoted for one week, he gets a minimum of one month pay and one month service time. If there are 100 players affected, the total cost might be $10M. Let the team absorb the added payroll and let the union absorb the extra service time costs.
