Five Days and Counting... begins its day-by-day look at the Indiana-Iowa football contest with five important numbers to know about Saturday's showdown.

21 – Iowa has won 21 straight games at Kinnick Stadium, dating back to a 48-7 win over Utah State Sept. 21, 2002. That's the third-longest streak in the country, behind Boise State (26) and USC (22). The last time Iowa lost at home was a 36-31 setback to Iowa State Sept. 14, 2002. The Hawkeyes have won those 21 games by an average of 24.3 points, including 17 double-digit victories. Indiana is the only Big Ten school that hasn't been a victim during the Hawkeyes' current streak, since Indiana and Iowa haven't played in Iowa City since 2001 – a 42-28 Iowa victory. Indiana last won in Iowa City in 1999, posting a 38-31 victory over an Iowa team that wound up 1-10 during Kirk Ferentz's first season as head coach.

98.3 – Average rushing yards per game for Iowa tailback Albert Young, which ranks fourth in the Big Ten behind Northwestern's Tyrell Sutton (154.4/game), Minnesota's Laurence Maroney (145.8/game) Wisconsin's Brian Calhoun (141.5/game). The 5-10, 207-pound sophomore has breathed life back into an Iowa ground attack that was non-existent in 2004. A year ago, Iowa averaged only 72.6 yards/game on the ground as a team and 2.0 yards/carry. This year's team is averaging 185.8 yards/game rushing, and its 11 rushing touchdowns have already eclipsed last season's total of 10.

17 – Total penalties in six games for Iowa, making it the least penalized team in the Big Ten. Iowa has been penalized for only 117 yards this season, nearly 100 yards less than any other team in the conference. Penn State is the second-least penalized team, being flagged 26 times for 202 yards. Indiana, meanwhile, is the Big Ten's most penalized team, being flagged 43 times for 332 yards. On average, Iowa is penalized only 19.5 yards/game, while Indiana has been backed up an average of 66.4 yards/game.

58.8 – Iowa is the Big Ten's best defensively in the red zone, allowing foes to score on 58.8 percent of the time when they are inside its 20-yard line. Hawkeye foes are only 10-of-17 in the red zone, including nine touchdowns. Iowa has been aided by some less than stellar placekicking, as its foes are just 1-of-5 on field goals in the red zone. This is a bad combination for Indiana, which continues to rank last in the Big Ten in red zone offensive efficiency at 70.8 percent. Indiana started the year 4-of-10 in the red zone, but is 13-of-14 since. That miss came this past weekend when Josiah Sears fumbled at the Illinois one-yard line.

180.5 – Passing yards/game for Iowa quarterback Drew Tate, which is down significantly from his 232.2 yards/game a year ago. A big reason for that is the improved Iowa ground game, which is piling up more than 100 more yards than it did a year ago. While Tate isn't putting up the same numbers that he did a year ago, he's been much more efficient. Last season Tate ranked third in the Big Ten in passing yards, but his Big Ten-high 14 interceptions contributed to a pass efficiency rating of 134.7. This season Tate ranks 10th among 11 Big Ten quarterbacks in passing yards, but he's second in the league in passing efficiency with a 151.5 rating. A big reason for that is a 65.4 percent completion percentage and the fact he's thrown only three interceptions in 133 attempts.
