We are taking a similar approach this year, but opting to store all the information in a MySQL database in the cloud (as well as the entire website). Of course, the downfall of this is that without a cellular connection we're sort of screwed.
Eventually I'd like to integrate Tableau, but we're just working with a simpler graphing plugin right now. I might run it locally off my laptop for the next competition if we can't get a good internet connection. It does make scouting much easier to just eliminate paper entirely. We also have an interactive system for data entry and automatically generated statistics based on teams.
