It's issues such as this that make me wonder why more dynasty leagues aren't best ball and why so many owners are against it. My dynasty leagues have anti-tanking rules but every year we have people that leave guys in on bye usually due to being busy that weekend or something. Typically it is a warning the first time and the team is penalized the second time. This has been exacerbated when the NFL went to Thursday games every week. I got screwed in one league two years ago because one team started a guy on Bye on me and he would have won otherwise and then a different team did the same thing a few weeks later. Since it was a first offense for both, there was no penalty outside of a warning. So instead of the #1 pick and Zeke, I had the #2 and got Coleman. Another point in its favor (that some may not agree with) would be Best Ball would eliminate subtle tanking where I stick a guy on my bench that I think will have a good game over another. Obviously it wouldn't stop guys from trading for players on IR or such, but they are giving up something of value to do so to acquire those guys.
I've heard the arguments that owners want to be able to control who they put in and pick their matchups, but bestball gives you the benefit of those guys you would have put in if they blow up either way. Only thing I can think of is that it is a pride issue of being able to say I started so and so over so and so and they blew up. Or that people want that control as a possible competitive advantage over other owners who don't play matchups as well as they do. But I would wonder if that really happens so much that it would make a huge difference, maybe in the old days when information wasn't all over the internet on matchups and injuries, etc. I guess I could also see an issue with the hoarding of defenses or kickers, but a team is sacrificing a valuable roster spot to carry extra ones.
Open to other folks thoughts, maybe I am missing something?
