Using ICHawk's link of college defensive stats for 2008 in this thread, Iowa's 2010 defense would have ranked 1st against running teams with 4.25 points per game, ranked between 53rd and 54th against passing teams with an average of 24 points a game, and ranked between 92nd and 93rd with 31 points against Wisconsin.
This was the post I made in an earlier thread about KOK showing my research of Iowa's 2010 defense stats. It was easier to repost it than use a link because the thread is about 5 pages long... Here it is:
These 2010 defense statistics rating Iowa 7th in defense and 17th in scoring defense are, IMO, misleading statistics.
Here are the results of the 2010 season for Iowa:
*Iowa 37 Eastern Illinois 7 - good showing by the Iowa defense.
*Iowa 35 Iowa State 7 - good showing by the Iowa defense.
Arizona 34 Iowa 27 - bad showing by the Iowa defense on that last Arizona scoring drive (the big play was a passing play).
*Iowa 45 Ball State 0 - good showing by the Iowa defense.
*Iowa 24 Penn State 3 - good showing by the Iowa defense.
Iowa 38 Michigan 28 - Iowa held on to win after a big lead at half. The defense knocked out the starting QB for Michigan.
Wisconsin 31 Iowa 30 - IMO, terrible showing by the Iowa defense.
*Iowa 37 Michigan St. 6 - great showing by the Iowa defense.
*Iowa 18 Indiana 13 - wide open dropped pass in the endzone costs Indiana the win - mediocre showing by the pass defense. IMO, a good example of how the bend but don't break defense can be successful or unsuccessful in a blink of an eye and is successful or unsuccessful to no fault or achievement of the BBDB pass defense.
Northwestern 21 Iowa 17 - Bend but don't break pass defense bent and broke (as it always does against Northwestern).
*Ohio State 20 Iowa 17 - good showing by the Iowa defense.
Minnesota 27 Iowa 24 - Iowa couldn't stop Minnesota's running attack (quite disturbing since stopping the run is the Iowa defense's forte)
Iowa 27 Missouri 24 - defense couldn't stop Missouri's pass offense until the last drive. Iowa's defense wasn't good.
Iowa's defense gave up a total of 7 + 7 + 0 + 3 = 17 points in 4 games or 4.25 points per game to teams their defense should have dominated: E. Illinois, Iowa State, Ball State, and Penn State (strong running offense and weak passing offense).
Iowa's defense gave up a total of 34 + 28 + 13 + 21 + 24 = 120 points in 5 games or 24 points per game to teams with good passing offenses: Arizona (I acknowledge some of those points were not given up by the defense), Michigan (who passed exclusively in the second half), Indiana, Northwestern, and Missouri.
Wisconsin was a team with running power, superior athletic abilities, and passing abilitites who manhandled Iowa's defense scoring 31 points.
Iowa's defense manhandled Michigan State allowing only 7 points. The difference, IMO, between MSU and Wisconsin was the one dimentionality of MSU's offense, their running game.
Iowa's defense did a good job against tOSU. tOSU couldn't effectively pass. Iowa stopped their running game. Unfortunately, the athleticism of Iowa's defense was outmatched by the athleticism of tOSU.
Then there's that Minnesota game. Iowa couldn't stop the run. Was that because the field in Minnesota was icy? Iowa gave up 27 points.
To recap:
Iowa's defense averaged 4.25 points against teams with strictly running attacks and IMO, patsies.
Iowa's defense averaged 24 points against good passing teams.
Iowa's defense gave away 31 points to a good running, passing, and athletic team in Wisconsin.
Iowa's defense gave up 21 points to a strictly athletic team like tOSU.
Then there's that outlier game for Iowa's defense: the Minnesota game.
As you can see if you aren't yet bored, Iowa's defense is good against a running offense, is mediocre against a good passing offense and is awful against an offensive team with skills.
Using points per game, is Iowa's defense good? It depends what kind of offense it is trying to defend.
I don't expect to win over ideologues who love defense. Ideology is a problem on HN. I just want Iowa to win games.
