I feel like we could potentially make this a lot more compact with something like Rankings: map<number, PollRanking>; where the int key is the team's poll position for the given week (1-25), and pollRanking is a struct declared like:

class PollRanking {
TeamID: number;
Votes: number;
FirstPlaceVotes: number;
}

Not sure how complicated it would be to make that change at this stage, so I'm willing to let it stay as-is if preferred.
