Frost has a bit of a conundrum on his hands picking a starting QB. McCaffrey is a better runner, but as the Illinois game proved, is a very limited passer. At his postgame presser, Frost bemoaned the inability of McC to hit wide-open WRs on deep throws. This was evident a couple times when McC was rolling out/improvising that he had WRs breaking free along the sideline for a long TD and he threw the ball 5 yds out-of-bounds. Martinez may be the better choice because altho he is a turnover machine, he has a much better chance of completing passes down the field. Frost will review the Penn St. tape and see that Iowa was able to bottle up Levis (who's a run-first QB), but that their passing QB found gaps in Iowa's pass coverage. I wouldn't be surprised if Martinez started, and McC was brought in with a package of specific run/option plays for him -- or vice versa with McC starting and then Martinez brought in with specific set of pass plays to run. Either way, Iowa's defense is not a great balm for a struggling offense.
