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

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. A contributor at FootballDiehards.com and on SiriusXMFantay'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 this week: Ryan is extremely high on Chargers running back Melvin Gordon in a matchup against the Raiders that has an Over-Under of 53.5. 

"Gordon ($8,600 on DraftKings, $8,700 on FanDuel) is the highest priced player in this game on both sites," Ryan said. "He is a cash game staple and is worth paying up for each week. He is hitting value on both sites 75 percent of the time. Daily lineups should be built around Gordon."

Ryan has also identified a receiver who has underperformed in 2018, but is still a must-start in what Vegas says will be a high-scoring matchup this week. This pick could help you cash big in Week 5. 

So how can you use Vegas lines to crush your Fantasy lineups this week? And which struggling receiver should you stick with? ... 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!
