In any sort of handicapped league you are going to get pushback when you aren't actively trying "to win". While your motives seem pure and reasonable, there will always be those who suspect ulterior motives when people don't appear to make shots that should normally be makeable. ESPECIALLY if you play as well as you indicate. That's just the way it is.
Accusing you of sandbagging is pretty serious, in my opinion. These folks must be pretty annoyed. Yes, you pay the same amount as everyone else, but if they perceive you to not be trying your best against them, they will automatically believe you are playing to adjust your handicap, or that your actions will adjust your handicaps regardless of motive. No matter how you explain it, there will be some who think you have some motive to lower your handicaps, even if they can't see why immediatley. And that's when it gets ugly.
I am quite sure that you can find opportunities in your matches to play a legit safety every now and then, for practice sake.
I wish you luck.
That would change everything if there was actually a motive, an incentive. But there isn't. And the fact that I have only played once & my teammates are not that strong kinda lends belief that there's more to it than is being said. My team won the last 3 years straight so we broke it up & formed new, weaker teams this season. And not everybody is annoyed. It's only one officer & her friends.
