If Carr can’t go next week, Haener should get the start.

Carr won't even make a difference. The play of the guys in front of these QBs is why Carr hasn't played the last 3 weeks, why Rattler didn't have a chance and why the myth of Haener was deflated in 17 minutes of football.
If the "myth of Haener" was deflated in 17 minutes, then the "myth of Rattler" is deflated after 2.5 games of football.

If you disagree with that, then you are obviously biased and using double standards.
