The macro-level key now 4 years in for Jim Harbaugh going forward is to recruit and then develop guys much better on offense to match the ongoing NFL player development and replacement level on defense.
Top recruits pay attention to program results and draft picks/NFL careers. Not single game results. Recruiting a young man passionate about the game of football yet staring at a 3-4 year slog of school/"school" and constant practice begins with showing them how you got similar young men into immediate future wealth and NFL opportunity.
Harbaugh, Don Brown and Michigan are consistently doing this with defenders at all three levels. Bush and Gary will further that trend. Other guys from the pipeline are getting meaningful snaps in the NFL.
A similar trend has to start on offense. We need legitimate 1st and 2nd round talent developed NOW. In 2019. And from there a trend set up. There's no more excuses. And at all 3 levels (line, QB/RB, WRs). If it can't be done with this staff then this 10-3 late season "meh" might be the ceiling. Get it done!
