For players, the news is even better. Assuming that owners behave as rational economic beings--and there's plenty of evidence that they behave more like Wilma Flintstone and Betty Rubble with charge cards, but we'll set that aside for a moment--a lower revenue-sharing rate means the monetary value of a free-agent signing goes up. If you think that signing a Barry Zito will bring in an additional $20 million in annual team revenues (thanks to extra ticket sales, increased value of your media contract, and appreciation in the value of your Barry Zito bobblehead collection), and your effective marginal tax rate is 40%, you'd consider it a profitable venture to sign him if you can do it for less than $12 million (60% of $20 million) a year. Cut the marginal rate to 31%, and Zito's value jumps to $13.8 million (69% of $20 million) a year. By percentage it doesn't seem like a lot, but a few commissions like that and your agent can buy himself a new Caribbean island.
