Here are the complete Week 15 Raanan Rankings:
(Note: The Raanan Rankings are comprised of a total score for each team from five categories — offense, defense, special teams, quarterback and coaching. The scale for each category ranges from 1 (lowest) to 5 (highest). Ties for teams with identical points totals were broken based on number of wins, head to head matchups and quarterback ranking.)
