You're missing the key variable: elite quarterback play elevates the entire system. Texas won the SEC because Quinn Ewers had a 72.4% completion rate against top-20 defenses, not just because of scheme. A great QB makes protection calls and creates off-schedule plays that no system can diagram. Your argument ignores that Texas returned only 3 offensive line starters last year and still led the conference in yards per play. True talent at QB transcends chaos, which is why programs like Georgia and Ohio State aggressively pursue elite transfers. Development matters, but you can't develop what you don't have. The portal arms race is about acquiring that ceiling-raising talent your system can't manufacture.
