I don't really mind giving up some to the away team but let me raise my prices by a few bucks just like ALL other sports do for their playoffs.
I think that one of the best ways to improve your abilities in this game is to stop trying to think of it in terms of the real world, so I hate to chime in on virtually every thread like this with the same refrain, but it deserves repeating: stop comparing your division 5 team to major league sports.
Within in the North American context (no idea about Europe, Asia, Africa or Latin America) minor league teams do significantly worse at the gate during the playoffs than they do during the regular season, often having the worst attended games during the playoffs or being forced to comp massive numbers of tickets (and almost always having to make playoff tickets free to season ticket holders) in order to prevent playing to an empty house. Minor league teams rely heavily on actively selling tickets, particularly to groups, and in basketball minor league teams are often not the primary tenants and are forced to take bad dates (i.e. lots of monday, tuesday or wednesday nights) during the playoffs because that's all that's available. With less than ideal dates and very little lead time to sell group packages playoff games are often attendance nightmares for minor league hoops teams in particular. I would say that the vast majority of minor league basketball teams in North America lose money on each playoff game.
More generally, I don't believe that there is single minor league hoops team (including the D-league) in North America that turned anything resembling a profit in the last 12 months.
Short version: Comparing BB directly to basketball is not going to help you get better or help you understand how the game works. And if you really wanted to compare BB to real basketball then you should have a 40% full arena during the playoffs and your net income on the year should probably be in the negative hundreds of thousands of dollars.
