Vegas lines are more than just a predictor of the final score of games. They also can be a secret weapon in Fantasy football.

Before you start using them to crush your Fantasy week-to-week lineups, you'll want to hear what Fantasy analyst Jen Ryan has to say. She's a contributor at FootballDiehards.com and on SiriusXMFantasy's "Football Diehards" show. Ryan, who has been an FSWA finalist for "Best Football Series," goes in-depth every week on SportsLine on using Vegas lines to make Fantasy decisions in both season-long and daily.

One tip we'll give away for Week 1: Ryan is high on wide receiver Calvin Ridley to get into the end zone against the Seahawks. 

"It only takes one, and we all know the general Fantasy consensus on Julio Jones and his lack of trips to the end zone," Ryan told SportsLine. "Ridley's scoring efficiency blows Jones' out of the water, with the former seeing far more targets in both the 20-zone and the 10-zone."

Ryan has also identified an undervalued quarterback who should make a significant impact as a runner in Week 1. This player can give you a huge edge in your Week 1 DFS and season-long Fantasy picks. 

So how can you use Vegas lines to crush your Fantasy lineups this week? And which undervalued quarterback should you be all over? ... Join SportsLine now to see Jen Ryan's guide on how odds and Fantasy can work together, all from a proven Fantasy and Vegas expert!
