WIS promised me they would create more detailed guidelines weeks ago. (It's not just about MikeT23's recent dealings, so no one should blame him.) It is very dubious that mere guidelines could solve the tanking problem, while not punishing honest efforts.
There needs to be a call that either the Commish makes, or a vote, akin to vetoing a trade (pehaps with the Commish getting a more weighted vote) along with evidence of tanking.
Evidence is essentially that a GM did not make moves to feasibly and reasonably attempt to improve his big league team where he could, while it languishes in last or nearly last place.
