What are the rules for position changes again? Example, hasnt Melo started 10 games at PF but he still only has SF status?
Taking them on a case-by-case basis this year. Most likely no one will be changed so late into the year. You can pretty much safely assume -- so late in the season already for fantasy purposes -- all players will be staying the same. He was slated as just a SF on all depth charts and on all materials coming into the season. I would not look for anything to change barring anything drastic.
