I disagree. You play an opponent, you have real game film to analyze, see what isn't ideal and where there is work to be done. You may see a position or two where your starter isn't performing as well as the guy behind him. All kinds of good info.
Some day what or whoever controls CFB will allow spring and/or fall scrimmages and practicing together among teams. CFB is looking more and more like the NFL (for better and worse) and if that is the reality, they will move toward an off and pre-season that helps get teams ready to play at a higher level. As it is, Akron, W Mich, and the Thundering Turds are the de facto pre-season schedule for 2024 OSU.
