I lost Edwards the day after my draft but was able to get Mitchell during the 49ers game when I saw Mostert get injured. It is a quirk in the yahoo leagues that you can cut a player from your bench and add a free agent while their games are going. You cannot play the new add that week but you can grab them before they go through the waivers process for the next week. I feel like it is cheating but since it is legal to do, I took advantage of it.
