So, I play this thing called Learned League, which is a trivia game that gave me this idea. In Learned League, you answer trivia questions, but you also assign a point value to the questions your opponent answers. Whatever. Point is, LL actually tells you how well you did on this aspect of the performance.
In Ottoneu, I know how I perform at a team level. But how good am I at choosing which players to start and which to bench? It would be interesting to know if I am particularly good or bad at this. Roster construction is part of being a good manager, but so is gaining a marginal advantage by being good at starting/sitting players according to matchups, etc.
The way that you would do this would basically be calculate the total points your team could have scored on a given day with an optimal start/sit strategy. Eg, let’s say you scored 100 points, but your catcher spot gave you -4 and you had a catcher on the bench that did +6. So with a better start/sit strategy you would have scored 110. Assuming all other things equal, you would get a -10 “start/sit score” (or whatever you want to call it). This could be generated separately for lineup and rotation and summed for the team.
I think this would be a really interesting stat to add to the game that would get players thinking more deeply about this aspect of performance, and it would just be fun!
