but even non tankers have normally cheaper roster then other and can earn money while relegating so they have savings
Relegated teams can save too much, this is the problem and not the draft pick, don't you think ?
Revenues : tv contract + merc + arena receipts
TV contract is the same for everyone in the league, differences in merc are marginal.
The main variable is the arena receipts.
Expenses : players salaries + staff salaries
The rest are not fixed costs. Most teams have cheap staff, again the difference is marginal.
The main variable is the players salaries.
I will try to get into numbers but there are thousands of leagues and of different levels, so for the sake of simplicity, let's keep it to very rough numbers.
Arena receipts will vary 100k in top leagues, 50k in lower leagues.
Players salaries differences can easily be two or three times these amounts between the stronger and the weaker teams, even if they are not tanking.
There is the imbalance.
I am aware that successful teams shouldn't get too much financial rewards or they will be uncatchable (much like IRL in open leagues), it's a game. But there should be a significant difference between top and bottom teams, significant enough to cancel the financial reward of losing.
The economy of BB needs a total rethink. Yeah, I know and I am sorry... but small patches like we had until now won't make it. They will correct and balance the overall numbers and had put some coherence but they have not repaired its structural flaws.
What incites to tank is the cash. Fix the economy and you fix the dramatic tankings.
