With four rounds under their belts, seven Northern Illinois squads remain undefeated at the 2015 IHSA Finals in Peoria. A record 146 8-person teams have entered the competition (with up to 4 alternates allowed per squad). 

Lincolnshire's Stevenson High School holds the top tiebreak after trouncing Fremd High School (Palatine) 68-0 in round four. Freshmen are playing their first three boards, with Alex Bian, James Wei and Conrad Oberhaus all posting perfect 4-0's so far.

Junior Allen Guo, Senior Philip Engstrom, Sophomore Rahul Dhiman and Sophomore Adit Ghosh are all perfect at boards four through seven. Stevenson's lone blemish was a third round loss on board eight.

Also in round four, New Trier (Winnetka) upended IMSA (Aurora) 51-17.

In the battle of the North's, Naperville North womped Niles North (Skokie) 54-15, and in the battle of the Central's, Hindsdale Central smoked Naperville Central 49.5-18.5

Hindsale Central's victory was typical of several others among the so-far undefeateds, demonstrating that depth is as important as top talent in the eight-board format:

• Naperville Central's board one, Senior Andrew Shao, posted his team's only victory in the team loss to their neighbor to the east.
  
  
• Glenbrook South (Glenview) upended Benet Academy (Lisle) 43-25 despite losing board two and drawing on board one.
  
  
• Neuqua Valley pulled a similar feat against Highland Park 35.5-23.5 despite losing board one and drawing board two. (Board 4's result is unreported).
  
  
• Evanston Township defeated Lane Tech (Chicago) 40.5-27.5 while drawing on the top two boards. 

Perennial powerhouse and defending champion Whitney Young redeemed its third round 37.5-30.5 loss to New Trier by shutting out Lemont High School 68-0. Whitney Young holds the top tiebreak among the three dozen 3.0/4 teams.

Competition continues today (February 14) at 9am with round five.
