Thinking outside the box....
I wish the league would allow an opportunity for both team to choose the refs. Sort of like choosing a jury.
I mean since there are no ulterior motives from the refs and since they always remain impartial, then I don't think the league would object to this. If anything, it would be a gesture from the league that their integrity is well intact.
Its an interesting idea. It would only work during the playoffs, because of the time and logistics involving in picking the ref crews. Heck, it would probably only work during the Finals.
Honestly a much better gesture from the league would be to open their internal reports on referee audits.
I have to imagine that with the amount of games that each official refs a year, you'd be able to see a clear baseline for individual players, teams, venues, etc..
