The GameDay Facts Play Analyzer app uses historical play by play data to analyze what will happen in upcoming pro football plays. The user can select a team, their opponent, and the situation based on quarter, down, yardline & yards-to-go. The app will display the overall probabilities of the types of plays & the detailed results of those plays (TD %, turnover %, etc...). Because most teams don't play each other very often, the app can't compare directly what teams do against their specific opponent. Instead, the app shows the stats in 3 ways: the team vs all other teams, all other teams vs the opponent, and the league average.
