To manage short term injuries, I would like to see a button which does the same thing as the current "Ask manager for lineup button", but for just one game. Now, when you have someone in your lineup who's injured, but not for long enough to be put on the DL, you have to manually adjust your lineup. This button would generate a working lineup for just one game (for example, by simply replacing the empty spot in the lineup with the backup in the depth chart). It would save the trouble of manually adjusting your lineup to replace someone who's only going to be out for a couple of days.
This, as well as the ability to save lineups and depth charts (
Suggestion?: Save lineup/depth chart), would, in my opinion, make a huge difference in the amount of work day-to-day management takes.
