When I prepare a new season (roto), I use a custom tool that looks like Analysis Monster (way worse), in order to make batch drafts and see how balanced and efficient it looks. It's based on the season projections and for reference, I input the higher and lower score in each cat over the past few years, divided in decile (12). It gives a virtual total based on the 9 cats, so I can compare batches with each other (the higher the result, the better)
So the idea would be to have a blank Analysis Monster, where players can input the players they want, and the higher/lower stats that make sense for them in each cat. The advanced standings feature would be great to add some granularity because deciles would be so arbitrary.
I know roto players are far from being a majority here on BBM, but that would be really great ! and save me a lot of time tweaking my excel sheet...
