How are the various teams looking in terms of returning starters? For Green, there should be three for sure on offense (Tyson Hunka, Mike Schaal, Nolan McKendry) and six on defense (Schaal, Evan Reed, Rhon Bruce, Anthony Fortunato, AJ Fortunato, Anthony McMichael). Also, if he is healthy when the season starts, Antonio Martin will certainly be a starter on both sides of the ball.
Guys who I expect to see step into starting rolls are linemen Cohen Lynch (listed at 285!), Dario Lombardi, who missed most of last year with an injury, as well as Kaden Gregory and Evan Georgiou at WR. Looking at the roster on MaxPreps, there is a fourth Schaal brother, Luke, who will be a sophomore and is listed as a linebacker. If he's as good as his brothers, he might get some varsity playing time. Even more ominously for the rest of the league, there is a fifth Schaal brother who is an incoming freshman and is listed as a defensive end.
Lastly, there are 32 incoming freshmen listed on the roster, which is very, very encouraging.
