I provided this answer to the question How do NFL players know a fair catch has been called?
It was downvoted by 2 of the moderators since
it's just your supposition, and not something from either your personal expertise nor documented in the rules or official commentary
I do agree that I hadn't originally provided a reference, and so it was not complete. Though I don't see how one self declaring they have expertise on a field is relevant or can be verified!
Anyway, I do agree the answer was not originally sublime due to lack of resources. What I'm trying to understand is why was it downvoted by mods? I've been around for a long time here, and our practice has been to downvote bad/wrong answers; otherwise if an answer is not up to expectations we leave it.
So have we set a precedent to downvote answers that don't have a reference? I was off for a month, so maybe I missed that. Doing so is harsh, specially for a site that doesn't get that many posts and is gonna nip activity of any new users in the bud immediately. Also users will pick up this kind of behaviour when it's clearly declared by the mods in the comments. Unless we wanna downvote any answer that lacks a resource moving forward, I don't think we should be downvoting posts just due to lack of resource.
