This post appears to be a combination of ignorance with maybe a copy of a report by one of our opponents on how Iowa can "maintain their offensive underperformance".It is accurate in the sense of that's how they practice. It's standard practice at every level of college/pro football, because the risks far outweigh the positives.
If your QB gets hurt going live in practice, you're basically ****ed. They've taken starters' reps, developed a rapport with the OL/WRs, makes their reads a certain way, understands the offense and audibles, etc. If you have to go to the 2nd guy, not only are you likely getting a downgrade in play, but now you have to get the rest of the offense used to his cadence, timing, throwing style, etc.
It's not even close to worth it. If it was, more teams would ditch the red jerseys, but they don't.
An attempt is made to make the parts of offensive football fitting together sound like the parts of a swiss watch. They aren't, especially not Iowa's. Part of the reason players get to this level is their ability to adapt-to different styles, timing, leadership. etc. That adaptation is accomplished at practice. Any setback is far exceeded by even a 10% improvement in QB play. And Iowa's offense needs strong QB performance more than most teams because of the need to offset scheme deficiencies.
So Iowa MUST find their most productive QB and the one with the broadest skill set. The only way to do that is game=conditions environment. A risk? Yes, but one they can't afford not to take.
Not that what others do should be followed because WE need to find solutions to OUR problems, but you're also wrong about others. OSU won a NC with a third string QB. The starter got hurt in fall practice (not in the spring when he would have had time to heal). They took a risk because risks have to be taken when aiming for the top. And because of their overall talent, finding the best QB is more critical to Iowa's sucess than it is to OSU's.
There are countless other examples of teams doing whatever is necessary to find the best guy in spite of some risk--college spring games, NFL preseason games,... The largest risk possible is not doing whatever needs to be done to truly find the best option.
