NFL Betting Preview for Giants vs. 49ers odds on Thursday Night Football

The arrival of Thursday Night Football means tons of betting opportunities from all of the best U.S. sports betting apps:

The New York Giants (0-2, +10 spread) are visiting the San Francisco 49ers (2-0, -10 spread) on a short week. The game appears lopsided on paper, but Thursdays are never a straightforward affair, even if one of the game’s best players isn’t suiting up.

The G-Men overcame getting outscored 60-0 in their first 90 minutes of football this season before putting together stellar comeback to win in Week 2 and level their record at 1-1. That said, losing Saquon Barkley just in time to play perhaps the NFL’s best defense is awful timing.

After allowing 28 points to the Cardinals, it’s easy to see Christian McCaffrey, Deebo Samuel and the 49ers putting up some points on them Thursday evening as well after scoring 30 in each of its first two games against strong defenses.
