You willingly take over a crappy team so you get the honor of the record, if you really care that much about your record dont take them over.

The second idea isnt bad, help the competitive balance.

The second idea can have horrible consequences.  What if you have a less than scrupulous commish who tweaks the abandonment's pitching (or lineups) to his advantage if he ends up playing the team in question?

Seems like something that you'd want to avoid.

How about having the last team that played the ML team take over the team?  With 3-4 game series, that would be for a day to a day & half.

Only control lineup & pitching rotation & settings. Can't make trades, promote, etc.

Ability to abuse would be smaller than if the commish, or any other player, had complete control.

I think the good it would do in getting 0 SPs out of there and injured players on the bench would outweigh the potential for bad.

They'll never do this.  Would probably take a lot of programming to create this sort of limited access and to rotate control.  Plus there would have to be a change to the interface to give temp access to a different team.
