What factors affect NFL predictions?

Predictions of the results of NFL games are affected by factors such as the record of the teams playing, key injured players, the weather forecast, which team has the home field advantage and key personnel matchups. These factors are considered both in picking winners and setting the spread.

The favorite in any given game is determined by analyzing the statistics and comparable data of both teams, including previous games against similar opponents. Predictions are then made based on which team, in the opinion of the experts, has the most favorable matchups and opportunities in the game. Injuries to key players can greatly impact the predictions, regardless of the teams' records and recent history.
