Yes, this.
I mean, someone said up above that coaches don't really like spring ball games. But it was the coaches who invented them. And the purpose they serve remains valid to this day: culminating event of spring practice, chance for players to put into practice in game-like conditions all the techniques they've been working on for a month, and even more importantly a chance for the offensive and defensive squads to get game-speed practice at teamwork against live competition.
I just don't see coaches suddenly saying, hey, we never liked this, we always just did this for the fans. Because they didn't. They did it for the team.
I'd think they still would. Maybe they'd want to dial down the commercialism if they could. But they'd keep the game. Wouldn't they?
Only caveat to all that is: injuries ... but then, injuries are a risk any time you go man-on-man at full speed, whether its a game or line drills 1-v-1s.
US Army has a catch phrase: train the way you'll fight. It's super important for success. And I'd think it's just as valid in football as in the military.
