What do you mean by 'pass judgement'... You mean watching games and making observations? I'm not aware only Texas fans do this.
Sark has a pretty good record of training and putting QBs in the NFL. Card knows this, which is why he won't transfer. Long term he'll be a better QB by playing for Sark. Long term Texas will be a better football team for having Card as a starter.
He just wasn't ready as a freshman to walk into a hostile stadium and run a new offense. That's a pretty tough assignment, but also a reality of big time football. No one is holding it against Card that he wasn't ready yet. Every Texas fan I talk to looks forward to what he'll do in the future.
If you want to talk about emotions and being pissed, think about the opposite side of this... if you kept throwing Card out there before he's ready. That's a recipe to crush a young QB - destroying any confidence he has himself or fans have in his abilities. Sark is protecting him with this move, and in the press conference basically said this gives Card time to breathe.
Card needs a little time to self-reflect and let last week's game become a character building experience. As opposed to throwing him back out there and maybe turning into a soul crushing experience.
