By looking at the players in the class, talking to HS coaches, and comparing to past classes. No real mystery.
Why do you think it's as good as past classes?
It was bang-bang for sure. But watch it again, the ref panicked. He didn't signal forward or backward and was actually out of position and then panicked, blowing his whistle and waving it dead.
Pretty obvious that's backwards or extremely close - it sure as hell isn't forward. Lance's entire body was in front of the line and it hit Watson in the chest as he was on/behind the line every so slightly. No?
