This discussion has been put up many many times.
5th place: certain of staying in the league, but less training, less revenue.
6th place: more revenue, more training (realy?? since you might need to field your best all the time to keep your head up, so maybe you can't field those extra players and your best just play a lot more minutes...), possibly better draft.
the fact is, like Crazy already said, promoting in BB is hard, so preventing dropping a league is something that is worth money.
In the end the managers can still decide to trow some games at the end of the season to finish 6th instead of 5th if they realy, realy love to be 6th instead of 5th. If it is THAT important to you to get the little more revenue and training, you as a manager must make it happen.
I will not argue that ending 5th does cary these annoying downsides of possible less training, and less revenue, and also a later pick in the draft, but only to be safe from relegation is worth it for many, and that is how the BBs think about it as well, which is why they designed it to be this way...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
