The final score of a preseason game does not matter. We all know this. By the 4th quarter you have the practice squad in or you face a team like the preseason champion Ravens.
However, our first unit didn't create a scoring drive the entire preseason.
Saying that matters is not the same argument as saying the final score matters. We've watched that translate into the regular season for decades.(even Osaka days, our first team offense didn't roll out there and dominate against the opposing starters)
The coaches didn't trot out the starters in the 3rd game so they're confident though. Based on history I'm skeptical. On paper I'm optimistic at least.
