The Giants open the 2018 season as home underdogs to the Jacksonville Jaguars at MetLife Stadium.
Adam Levitan thinks that the line is at 3 because of the "massive" coaching upgrade the Giants got this offseason and that Eli Manning's splits with and without Odell Beckham are absolutely drastic, really, really massive."
Levitan added that right now "the sharp money, the big money and sophisticated betters are mostly on the Giants so far."
Pat Mayo said the line of three points was impacted by questions about the Giants run defense as well as their ability to limit turnovers.
Mayo said that "ideally the Giants quell the run-game, lean on Saquon Barkley to do the heavy lifting and capitalize on a big play or two from Odell Beckham. That is the path and even then it still may not be enough to cover thre three points."
