Yes, all at Homewood-Flossmoor HS in the South Chicago Suburbs. Craig Buzea is the HC and he took Portage to the '94 5A Title game. Zac Wells is the DC and he won multiple Sectionals and Regionals as HC at Merrillville. They also have Alexander Pratt, who did wonders as HC at Gary West Side, so no telling what he could do at a Region school. I believe H-F has a few more Region guys on their staff. I know Albert Evans (Portage RB/Purdue DB) was on their staff recently as well. H-F doesn't have a large MIC'esque football stadium, but their indoor practice facility and weight room are insanely nice. They're also paying coaches and teachers very good money.
Regarding Lake Central, they should be the Penn of Northwest Indiana. The size of school and socio-economics are nearly identical. Lake Central's problem, IMO, is they'll have to have a saleman as a coach to convince kids to stay in the Tri-Cities of St. John, Dyer, and Schererville. Of course, win too. Andrean and Chicago Mt. Carmel routinely get quality football and baseball players out of Lake Central's district.
