Sark should have a flexible game plan offensively for this matchup. If he doesn’t, then I dunno what the fuck he was doing all off season. The install should have covered various formations and ensured that each QB knew multiple plays from each. After that, you expand on those for the more complex aspects that you wish for the QBs to eventually memorize.
This allows for your offense to adapt/adjust rather quickly on the fly in games where glaring issues arise. Knowing that the O-line situation could result in you fielding group of youth/inexperience, proactive solutions should already be in place.
O-line protection decent/good? All plays /formations available
O-line protection average/poor? Narrow down to formations/plays that add pass pro assistance.
O-line getting absolutely obliterated? Nothing but plays that involve short/quick passes that prevent Defenders getting home, or max protect packages that have versatility within the package
There should be no scenario where an adjustment to the playbook cannot be made to handle the problem at hand.
