Eh, I disagree. We believed that Kubiak could ressurect Carr, there is nothing to ashamed of in that. We were wrong, eh, it happens. So we missed out on Cutler, Young, and Leinart - that doesn't make it foolish to draft Russell if we truly believe he can be our future.
If, 5 years down the road, we passed up Young in '06 draft, drafted Russell in the '07 draft, and made a Super Bowl appearence in '09 would it really look that silly?
Building a football team isn't about preserving your pride, it is about putting the best product on the field as you can. If you make a mistake, like we obviously did in '06, there is nothing wrong with recognizing that and moving past it. There is nothing more ominous than letting our '06 mistake dictate our '07 draft. Acknowledge your mistake, learn from it, and move on - don't let it control future decisions.
