I think games are "rigged" or tainted to keep them inside the spread at times. There is way too much money involved for phantom calls to be made without justification.

In football I think it's harder because of the way points are scored. 7's and 3's...
but if you watch the Colts SD game last year it was so obvious the Cromartie INT return for a TD that was flagged so late was suspect!

when you have instant replay and every one says there is no way it can be over tured and it is it's suspect.

The NBA is obvious though. When you hear... "you would never see that called at home" it's a damn shame.
