Itis, but again none is paying 8M, for any big man on those days. Yes in the past was that case. 8M is a money that are reserved for the very special players, and still i am not sure if anyone would pay that amount for any player...As about the income, i think that the max that we can have is 1M. Talking about my team, 856k, with well above to average merchandise profit (around 130-150k). So on that money we should be able to reassemble the best team that we can, but also have to worry for the future renew to our teams. For example, i recent sale a very good SG, that i bought him when he was 26 for 4.3M, and after several tries i got only 1.6M for him on his 29. I replaced him with a much much better player, but if i had than monster i couldnt afford to do it. Plus the taxes if you buy/sell very often, plus the Fun servery.
As far as about rebounding, its a skill that is very clear how it helps you to win games, and thats why managers are willing to pay for it. Not comparable. If we get a clear evidence that SB can have good value for money, i guess that people will start to pay for it.
And yes the salaries of the big men are absurd compared to the guards...
