Getting your Trinity Audio player ready...

1. Thank God it’s Friday: That’s when fans will flock to a pair of blockbusters–No. 2 Wheaton Warrenville South (8-0) at No. 3 Naperville North (8-0) and No. 8 Glenbard West (8-0) at No. 7 Hinsdale Central (7-1).

2. It is difficult to replace a legend: The season after Gary Korhonen–the state’s winningest coach–retired, Richards lost to crosstown rival Oak Lawn for the first time in 34 years.

3. Divine Providence: Look out in Class 6A because the Celtics are making another of their patented late-season runs, as evidenced by an impressive 56-21 victory over Bishop McNamara. If Providence beats Guerin on Saturday, it will be the most dangerous four-loss team in the playoffs.

4. Warren is playing like a Top 20 team: The Blue Devils (7-1) continue to impress, this time with a 50-25 victory over Stevenson. Warren’s only loss was 35-21 to No. 1 Maine South.

5. It’s win or go home for Richards and Morris: Both need victories in their regular-season finales to keep their seasons alive. Richards has made the playoffs 23 years in a row and Morris 20 of the last 21 years.
