SouthtownStar’s three things to know

1. A state titleholder swapped uniforms. Two-time champ Kris Williams will compete with Thornwood this season after winning the 106- and 113-pound titles at Thornton. The junior is currently nursing an injury but said he’ll compete at 120 for the Thunderbirds when he returns.

2. Lincoln-Way Central is a force. There were some question marks heading into the season after the state’s fourth-place team graduated a slew of contributors, but the Knights (9-1) haven’t lost a step. The team picked up notable wins over Minooka, Plainfield Central and Hinsdale Central to start the season.

3. Eric Schultz has bulked up.Tinley Park’s Schultz finished sixth in Class 2A as a lean 138-pound freshman. He’s packed it on for his sophomore campaign, winning the Stagg Invite at 170. Size runs in the family. His cousin, Derek, was last season’s state runner-up at 220 and is now redshirting at Eastern Michigan.
