It has always seemed to me that refs tend to favor (maybe subconciously) teams that win. Scoring points, fans cheering, lots of positive media coverage, etc. results in momentum that carries over to the refs. In the NFL when Manning was lighting it up his recievers got lots of marginal PI calls, Seattles defense while dominating got away with mugging opponents,
For a long time Texas has had superior talent and won a lot of games, the refs went along. Now that they aren't better, aren't winning all the time, the refs call stuff against them that in the past would have been ignored or gone in their favor.
If there was ever a fan base that had an inflated sense of entitlement it is Texas. They think they deserve every advantage simply because they are who they are. I love watching them panic and grasp for straws as they continue to struggle on the field.
We have already had some fun this year watching various inflated ego schools deal with losing. It would be a lot of fun to read Shaggy this year if Oklahoma manages to post hole them by 30+.
