I coach a small nation's U21 team and while it is true that there can be a little more cash around because you can stay in the top division with a weaker team they do miss out of so many benefits of playing in a larger country such as promotion bonuses, interesting and long cup runs, a wide variety of teams to play against and the needed level of difficulty to develop their own managerial skills. The B3 seems to be no different from local leagues where any team that has saved for several seasons can put together a ridiculous multi-million dollar team for a short run. This is not a small nation or a B3 issue, it applies to the entire game. To be honest it applies in real sport as well - just look at English Permier League Soccer - it is just that the NBA evens things out a lot with their salary cap.
It has been suggested many times that there be a salary cap for each division like the salary floor. Just like the NBA, teams could go above it but would pay $2 for ever $1 they were above it. This wont stop teams from having Venemous Scorpion like rosters, but it would make it a lot harder.
PS: I have no idea what this has to do with new teams. My suggestion forever for new teams is to give them at least one player who is solid right away and at least one player who is worth training rather than an entire roster of rubbish who should all be sacked right away and replaced with guys for $10,000 or less from the TL.
