the fact that they are husband and wife and the rift in player value since it is two weeks before the start of the season and dice-k still has major upside makes this seem like the husband wanted a more stacked staff and conned his wife into colluding on a trade
i would say this is worthy of a veto, your commish sounds ilke he is either in on it or a moron, but if he drafted a guy who is going to miss considerable time in the first round then i would more default to the latter
he also severly overvalues older players versus potential and is too ignorant to look at draft value, question the fact that it is a trade between a husband and wife
i think you are hosed though because as you said they are friends, and the commish doesn't have a clue
its not so terrible as it will completely throw off a teams worth, its just kind of in very poor taste.
i think you just have to suck this one up, and find a better league next year
