like saleh said. worse case scenerio is zach comes in for 2-3 games during the season and really he would have been fine with that. He didn't play awful when he had a decent o-line and run game to help. the bigger issue we have is the fact in 11 games we've had 8 different starting o-line combinations and 13 combinations total (both lead the NFL) we can't have any consistency on the line. add on to no real WRs outside of GW, and hacketts ass play calling there isn't a QB avilable that would succeed here unless it's a mahomes/allen type that can just do things mostly on their own.
