Yep, that is all Silsbee has to do is stack the box. Every team BV played this year has defensive coaches that know the same thing. In fact, they all tried to do it.
All Bellville has to do bash Silsbee into oblivion like they did to all the teams that Silsbee struggled with. Smash them on the line of scrimmage and run straight over them. Then overwhelm the Silsbee offense with physicality.
It is Bellvilles game to lose.
