The NBPA, meanwhile, has a positive balance sheet, with net assets over $90 million. This plan will cost between $12-15 million a year for them, which they expect to be more than covered by the increase in member dues from the cap spike. The NFLPA is years of dues in debt, much less covering a program that would cost about a third of what they currently take in as dues.
So looking at your updated links, I see:
NBPA: $33m in revenue ($15m of which is dues/royalties), $12m in expenses, $95m in net assets
NFLPA: $65m in revenue ($54m of which is dues/royalties), $40m in expenses, $217m in net assets
Does this change your opinion at all?
Obviously like you said, the NBA will easily cover there's in dues with the increase in cap spike, and can more easily cover the costs with their net assets as is, but the NFL still appears to be in a good place to handle things. Tack on a 2-3% fee to all all player salaries and we can get this thing off the ground.
