Five Days and Counting... begins its day-by-day preview of Saturday's match-up between Indiana and Southern Illinois with today's five numbers to note about the Hoosiers' match-up with its Division I-AA foe...

10 – combined points I-AA Southern Illinois has lost its last three meetings with Division I-A foes. A year ago, the Salukis squandered a 21-10 first half lead before falling to IU's week one opponent, Western Michigan, 34-28. In 2004, former IU defensive coordinator Joe Novak's Northern Illinois squad slipped past SIU, 23-22, when SIU went for a two-point conversion and the win with :54 remaining after a touchdown pulled them within one. Finally, Eastern Michigan knocked off SIU 48-45 in double overtime in 2002, a game in which EMU overcame a two-touchdown deficit in the fourth quarter to send the contest into overtime.

16 – Days Southern Illinois will have to prepare for this weekend's match-up with Indiana. The Salukis opened their season with a 49-0 win over Lock Haven on Thursday, Aug. 31, but had an off week this past weekend. That's reason for concern for the Hoosiers, who will be going up against a team that was ranked 17th in I-AA preseason poll. Southern Illinois has gone a combined 29-8 over the last three years, earned three I-AA playoff berths and won three straight Gateway Conference crowns.

303 – If you think IU will be able to physically man-handle I-AA Southern Illinois, guess again. Southern Illinois' offensive line averages 6'3 ½" and 303 pounds. The lightest of the bunch is 6-4, 290-pound center Will Justice, a preseason all-conference pick in the Gateway Conference. Left tackle Darren Marquez is 6'5" and 315 pounds, while right tackle Andrew Kernes is 6'6" and 300 pounds. Indiana, meanwhile, averages 6'3 ½" and 289 with its starting offensive line. Southern Illinois will run early and often behind that offensive line. In its shutout of Lock Haven SIU ran for 357 yards on 41 carries, or 8.7 yards/carry.

5.7 – yards per carry for SIU tailback Arkee Whitlock over his career. After his 15-carry, 134-yard effort against Lock Haven Aug. 31, Whitlock moved into fourth place on SIU's career rushing list with 2,547 yards. His 5.7 yards/carry average, meanwhile, ranks sixth in school history. The SIU record in that category is 6.61, set by current New York Giant running back Brandon Jacobs. During his one season at SIU, Jacobs ran for 992 yards on 150 carries, including 19 touchdowns. That same season, Whitlock was just behind Jacobs, totaling 959 yards on 151 carries, including 12 touchdowns. Jacobs was the Giants' fourth-round pick in 2005.

17 – Penalties for Indiana in its first two games, the most in the Big Ten. The Hoosiers have been flagged 17 times for 164 yards in penalties, which is also a Big Ten-worst total. The most common Hoosier penalties in the first two games have been holding (five times for 50 yards) and pass interference (four times for 49 yards), while they've also been flagged twice for personal fouls (30 yards), twice for false starts (10 yards), once each for an illegal block (10 yards), off sides (five yards), face mask (five yards) and 12 men on the field (five yards). In Terry Hoeppner's first year in Bloomington the Hoosiers ranked last in the Big Ten in penalties, getting flagged a league-high 74 times for 605 yards (55.0 yards/game).
