I hate it when you veto a trade
I've written about this before but it's among the subjects I feel the most passionate about. No trade should ever be vetoed; only in cases when there is clear and provable collusion between two owners should a trade be overturned. Otherwise, a trade must stand. Always. No matter what.
Part of the fun of fantasy football is that we all have different opinions on players. And no one can predict the future. A Week 1 deal of Calvin Johnson for Jeremy Maclin would have been laughed at, but in Week 10, the Maclin owner is loving life and the Calvin owner is hoping it's not too late to salvage something. So something that seems lopsided to you might not be lopsided in the future. Or seem lopsided to someone else.
It's not your job to manage someone else's team. Everyone should be allowed to manage their own team, even if it's badly. You don't think he got nearly enough for his star quarterback? So what? Not your team, not your quarterback. Again: The person dealing him thought he got a good deal, that's all that matters. Everyone should be allowed to manage their own teams however they see fit. Even if it's not in a way you agree with.
The art of negotiation is a skill. It's part of fantasy football, just like drafting, waiver wire pickups, making starting lineup decisions. It's a skill and part of what you need to be a successful owner. And it should be rewarded, not punished or neutralized.
There's a special level of hell reserved for the people who veto just because it's a deal that didn't involve them or because "it's part of their strategy." That's not strategy, it's being a jerk. Win on the virtual field, not in some technocratic loophole.
