On Iowa podcast was definitely my favorite with Dochterman and Morehouse. It's sad they're not still doing it - I like Hlas and Morehouse, but in a B+ way, rather than A++. Otherwise, I like Hawkeye Nation, Hawkeye Report and Hawk Central a lot - though I liked Hawkeye Report more two years ago when it was less goofy (I like some of the goofiness, though).
All Hawkeyes is awesome on Mondays when they have Don Patterson on. That podcast is mostly not the place for insightful analysis, but Don's segment is the most enlightening of anything on the podcasts.
