I run 2 leagues, going on 5 plus years for both leagues, and I hold sole veto right in 1 league, share veto rights with another LM in the other league. I state clearly for folks to protest if they feel that if there is collusion involved, but I have yet to veto any trades in either of my leagues.
I've heard of enough leagues where other owners would veto trades based on the fact that the trade would improve their competition, & no trades would be approved. If I think two owners are colluding, I would investigate, but a rookie owner getting hosed does not warrant a veto in my book.
You learn by getting hosed, & I shouldn't have to police inexperience.
