Las Vegas will post NFL betting lines on various games throughout the season even before the season starts.
These are very risky bets, however, because the bettor has no idea how well the teams will be playing at that time or what key players might be injured. Some bettors like to put some small wagers on those lines just for fun.
For the most part the early line on most weekly games comes out Sunday night after the completion of that day’s games.
There may be no line originally on the teams who play that Monday night because oddsmakers want to wait to see who wins that game and even more importantly if any key players get injured and would miss the following game.
By Tuesday morning the lines for all 16 games (if there are no byes) are posted at the various casinos and on the various websites.
