This seems like such a tough exercise to me, for the following reasons:
1. If you study Iowa year after year, the Ferentz "play 'em close" style and lack of explosiveness on offense results in a lot of close games. Iowa loses some of those games.
2. You are assuming in this type of analysis that Iowa has no key injuries. What happens if a player like Scherff has an injury that prevents him from playing in one or more of the first 6 games? What happens if Rudock goes down? (Sorry guys, I'm not sold on Beathard, notwithstanding the hype). Iowa does not have great depth on either side of the ball. We were relatively injury free in 2013, but that certainly was not the case in 2012, when two key linemen went down in the Penn State game (we did not win a game after those two key injuries).
3. Purdue is going to be better, and West Lafayette traditionally has been a very tough place for Iowa to play. Pitt will be sky high and they get us after an emotional rivalry game.
4. Iowa State gives us fits in most years.
5. Upsets happen in college football. The better team doesn't always win.
6. Unlike 2012, Iowa won two VERY CLOSE games in 2013 (Northwestern and Michigan). 8-4 could have been 6-6 (and it also could have been 9-3, since N. Illinois could very easily have been a win).
7. Although we should be slightly better on offense, I don't think we will be as dominant on defense with the loss of 3 truly outstanding LBs.
My realistic hope is that Iowa wins 3 of their 4 non-conference games, and then 4 of their first 6 conference games. If Iowa is 7-3 (4-2 in conference) and wins their last 2 games at home (which really could happen because I just don't think Nebby and Wisky are that good), they will be in the Big Ten title game (Nebby and Wisky each will have at least one conference loss going into the Iowa game, and thus losses against Iowa will have them losing the tiebreakers).
I think 9-3 and 6-2 in conference is absolute best case for this team (barring major injuries). Having them 6-0 after the first six is just crazy talk, particularly with 3 fantastic linebackers graduating. We can't replace those three dudes. Our LB play this year will be OK, but not nearly as good as it was last year. In short, we will score more points, but I believe we will give up more points as well. With the possible exception of 2002, Ferentz seems to do his best work when he has a dominant defense. I just don't think we will have a strong defense this year, but I sure hope I am wrong.
The podcast spent a ton of time analyzing the OPPONENT'S weaknesses.....but Iowa has weaknesses as well.
I predict 8-4 for Iowa and 5-3 in the Big Ten, (a very good season) qualifying for one of the better bowls, but no title this year. The defense simply will not be good enough.
