I'm not missing your point at all. It is wrong to intentionally run up the score, such as with trick plays, etc. I'm saying to you, the common fan perceives a score as "being running up" far more times than it truly happens or is the intention of the winning coach. For example, take your post above. You wrote about a team having a score of 70-0 at halftime. Immediately, an average fan who has never coached is thinking, "this is BS." But, across the country, several coaches both High School and College have the mentality or rule that their starters are going to play 1 full half. I agree with is, and if you are a passing team and spread offense and your offense scores 70 in a half, that's not running it up. If it's 63-0 with 55 seconds left, then yes, that offense should try and work on it's 2 minute drill and try to score before the half, then no starters at all in the second half. You wrote, "it's always safe to have backups in as to not have an issue." <--------That's false in my opinion. It is NOT always safe to have backups in to not have an issue to where it's palatable for the fans. In the first half, play your starters. There are only 10 regular season games in VA, that's it. 24 minutes in a half. You have to get your starters experience and ready them for the playoffs and allow them to work on their two minute drill because it's likely going to be needed late in the playoffs. After the first half, then I agree with you, backups should always be in if the game is out of reach.
I don't disagree with the premise of what you are saying, but I disagree some on how we get to the point of not embarrassing the opponent. For example, we agree that trick plays stuff like that, especially in the second half when a game is out of reach is wrong. Where I disagree is.......starters should play one half and try to score every second of that first half, even if up 60 to 0 and there are 59 seconds left. They should try to get 67. You have to get your starters the reps and plays and two minute situations that prepares them for the playoffs. In the second half, the starters should touch the field in the above situation. As for the backups that come in for the second half, if a pass-happy wide open offense, these second string kids should also be throwing the ball, even up 60-0 because that is what they do. It's there offense and the one they need to learn and be good at because they will own it in a year or two. That's all I'm saying.
