cwillis802, you started out by criticizing "ignorant" owners that veto, found that at least one owner that does veto in OLs is contrarian23 whom everyone here respects greatly and could hardly be said to be "ignorant". You then turned his own words around to make preventing the skewing of competitiveness in the league become vetoing to protect his own team's competitiveness which is not only not what he said but is the exact opposite - one is concern for the general good of the league, and the other is self-interest in the narrowest sense, however understandable as a factor in a competitive environment like a league.
Many owners do as pinotfan, another here who is widely respected and cannot be remotely accused of ignorance, and veto to provide a margin of protection for newbies who do not know how AAA works, what the relative values are etc. so that despite the obvious reality that new owners will rarely have the best teams, the playing field on which they are competing is relatively level, which is a good in the interests of all.
