None of these guys should be drafted high enough for it to make a difference to me. I'd say Jones gets drafted a couple rounds before Cabrera - but Cabrera has youth, potential, and position eligibility in his favor. It appears far from collusion, and is not lopsided IMO.
It's 2 teams trading players to hopefully better their teams, which is the whole point of trading. Veto it if you want to be a dick or you want to lay down a defensive veto.
I'm kind of surprised to see somebody even ask if they should veto a trade like that.
