Fantasy Football - good for the game?

Lately, I've been wondering if Fantasy Football is good or bad for the fans. There seems to be two extremes here as I watch my friends and myself act and react in a different way than I remember growing up (pre-Fantasy).

On the one hand, Fantasy Football is definitely good for ratings and advertising. More people MUST be watching, and watching more meticulously while buying up full-game packages just to see ALL of their roster play. This is great for the NFL, but is it great for us?

To ponder the negative, loyalties that make us who we are as fans go out the window. Feelings towards both liked teams and liked players are mutinied for the sake of the one player that is actually on the fantasy owner's roster. Excitement about a Chris Johnson touchdown turns to a "Well, that's okay" from the Titans fan who was hoping the TD would go to their own RB stud LenDale White. Even as I'm typing I am hoping that Cincinnati can score with less than a minute in the game down 5 points, just so that Hines Ward will have a shot at another catch, even though I hate the Bengals and my wife loves the Steelers.

I wonder also if the players are affected by the stats instead of the games they should be focused on.

Okay, the Bengals just did it, won, and my wife is mad at me. Point and case.
