LAS VEGAS - Las Vegas casinos think this weekend's NFL games will be the highest-scoring ever thanks to the league's replacement officials.

Oddsmakers say casinos are changing their expectations as interim referees add new variables to the game, changing its pace and the approaches taken by players and coaches.

Casinos haven't fully changed how they set lines yet because there have been only two weeks of games and referees might adjust. But oddsmaker Mike Colbert of Cantor Gaming says home teams will deserve an extra half-point in their favor if games are called all year the way they were officiated in Week 2.

Gambling expert RJ Bell of Pregame.com says casinos expect an average of 46.1 points per game for Week 3 -- the highest projected total ever for Vegas casinos.
