I really don't know much about either team. I have seen highlights and watched a few streamed game replays.
Broad Run is a very sound offensive team who seem to rely on the pass. Their starting qb has a strong arm and talented receivers. He puts the ball on the money and can throw his receivers open. The backup (brother?) has a good arm, but is not as accurate. I didnt find BR's running game to be overly impressive and I think this will be the key.
If BR cannot run the ball, Tuscarora's hawking defense will pin their ears back, pressure the qb like crazy and force bad throws. I like Tuscarora's db's and feel they can cover BR's receivers if the qb is requiredto throw quickly.
Tuscarora must also slow the game down and give their defense time to breath.
Hard to beat a good team twice. The best D wins this one. Tuscarora by 3. Maybe in OT.
