Depth Chart Limitations
There is a limit to the number of players you can put on the depth chart. When this error occurs, it is usually upon purchase of a new team or when a new GM/Coordinator tries to make changes to the depth chart. Also, if you attempt to put every player on your team on every special teams spot the submission will fail. Please click auto-reorder and update it. From there you will be able to customize it as you see fit. Use common sense when creating your depth charts.
