How about a trade committee of about 4-5 people (including yourself and whoever decides to help you) ? And you need a certain amount of votes from the trade committe for the trade to go through? Just like the previous sim league.

It'll definitely help if you beat the Celtics but all in all, I'm not too sure if you'll be able to catch up to them and grab the 4th spot. I hope you guys do though.
If needed I wouldn't mind helping, I have time on my hand but I don't have much experience with simming although I do have quite a fair bit of experience in sim leauges (been in about 10 or so).
That's probably a big problem. Although time is helpful for a commish, an understanding on how it works on everything is required as well. Try getting a program like Fast Break Basketball and learn it.
