Moving on, i am surprised that you consider 400k per season, for a division III team, regardless if it is a new or old team, inconsequential since it is not crippling!
More so, when there is an elephant in the room...
Futhermore, it...never ceases to amaze me, when people doing team economics and management on the fly, soooo easily, always forget MAINTENANCE COSTS!
It is common sense, that what we see as a weekly/yearly profit in our books, is not "true", since in order to replace your assets(players) because of aging, you will get less money due depreciation and/or wil need more money to replace them(without upgrading) due to inflation...
There is the elephant in the room again...
Yes, of course there is maintenance. And thankfully, it's more expensive the higher up you go - replacing top-tier talent costs significantly more than replacing III level talent, for sure. The whole issue about the gap between new and old teams? This is one of the things that helps newer teams start to bridge the gap.
You'll also note that since the new salary floor increases are essentially 30% for all leagues above 3, but that the TV contracts are higher by a good margin higher up, this erodes a little more of the advantage for teams tanking at top levels (or staying up in half-bot leagues with much lower salaries), which is the main purpose of the change.
Frankly, I think the main thing is that the idea that a team should ever consider it wise to tank and collect as much money as possible so they can buy future success is detrimental to the game. Thanks to the maintenance issue, I finally had to go through the painful process of getting rid of most of my roster and starting over with a new set of trainees - which, after having trained up a significant core of players and building around them over time was hard to take. I know another twelve seasons or so I'll be doing that again as well. But just sitting around skimming profit weekly and doing the bare minimum isn't something the game should encourage. If you choose to do so, sure, good luck with it, but when the best way of succeeding in a game is simply not playing it for a year or two, it's not worth playing at all.
