I think one of the reasons price reduction in the market is important is because it gives newer managers more of a chance to compete.
I haven't seen anything on the forums about it, but then I haven't really looked either.
I don't think raising the salary floor is a good idea. There are some teams who genuinely have difficulty getting along and shouldn't be punished for it over and above their tactical mishaps.
Perhaps an overhaul of the fan system would work? A tanking team - a team that constantly (not once or twice) loses by 30-60 - just doesn't get the crowds and, therefore, doesn't get the income.
