If people enjoy talking about it, there's no reason they shouldn't post.
If it bothers you that much, you can choose not to read the posts until the day that the deal is done either way.
Just ignore any Moss posts until you see one that says the deal is done or it fell through.
I like ALL of the Randy Moss posts maybe true maybe not, but its fun to read them...and it would be boring without not posting rumors and whos to say they are not true? Randy could possibly end up a Packer sure hope he does IMO...
