LaMarcus Aldridge just got interviewed by TNT and he said "We are trying to push the ball more for this game." 

Portland has not been scoring that much in their last couple of games, so you would think tonight's game is no dfferent..

I'm sure a lot of people took the under because of Portland's lack of scoring in their last couple of games.

As a recreational gambler, we do not have access to the pregame interviews by players and coaches, so we have no idea what the game plan is. However, a media person like Musberger and Michaels have press credentials, so they are allowed to interview players and coaches about the game plan and so on. or They have press friends that they can ask for inside information on the game plan. This would give Musberger and Michaels a huge advantage on how to bet on the game, especially on how to bet on the totals.

Portland plays a half cour style offense. They rarely "push" the ball, but tonight they pushed the ball and as a result, they scored 60 in the first half.  Dallas is a good defensive team, but the fact that Portland is playing an uptempo gives them more opportunities to score.

Also, Musberger has access to the players before game time and he probably knows some injuries that the public does not know about and it could affect the way the game is wagered.

Heck, I wouldn't be surprised if Barkley bet on every TNT games, because he knows or he has a lot of valueable info on how to bet on that particular game. Barkley could gather miscellaneous or intangible info that the public does know about, which could affect the outcome of a game. It's all legal, but it's unfair that these media guys have much more info to cap the games then we do.
