I think that the OP isn't accounting for the fact that Iowa's redzone execution (or lack thereof) was a big reason why the game ended up being close. Whenever you allow ANY team to stick around in the game ... the more that they believe that they have a chance to win.
Indiana is definitely not a great team.
However, Indiana is also capable of being a pretty dangerous team. Including this game, Indiana has been INCREDIBLY close this season to being a 7-2 team. Instead, they've dropped three games that they very possible could have won.
The ability to close games is the fine line that can separate winners from losers ... and good teams from not-so-good teams.
Heck, Iowa is good enough to be dangerous. However, the Hawks themselves are irritatingly close to being undefeated at this juncture ... and the very fact that we've lose 2 close games is simply reflective of the fact that we're not as good as we originally hoped to be. Of course, this teams has also faced plenty of adversity. However, at the end of the day ... we're fortunate that this teams still seems to remember that there's plenty to play for yet.
