For the last two years, ESPN has been working on a projection model which they now call Football Power Index. Some of the factors they've used to come up with this index include Vegas win totals, how many of team's starters will return, starting and backup quarterbacks, how teams performed on their offense, and also the team's defense and special lineup team of the last season. While this has been going on, San Francisco 49ers
has been busy in this offseason. Many people feel they've a higher chance of making it to Super Bowl finals. No wonder 49ers odds remain higher, especially after they were placed among the top 10 teams in ESPN FPI for 2018.
