What would you change

Other than "recruit better" what changes should be made to keep getting better and take the next step ?

Let's realize that last year Oline was crappy and receivers were total non factor. Both improved this season. 

1. Is it as simple as start practicing more zone ? Regarding "go more spread " I am suspicious we are headed that way the way we are recruiting slot ninjas (?). 

2. There is a lot of consternation re: scheme. Curious to hear Brian's take but can a coach (hello space coyote or Magnus et Al) point out if our offensive scheme is truly "outdated". I know someone posted getting Jedd Fisch, but is there any doubt Harbaugh won't at least consult with him to get more ideas about offensive upgrade ala calling bill bilichek to get D brown ? 

3. Had fun watching this team demolish most of the teams on schedule. Feels like this is Michigan's floor now. I won't call this overachieving. 10 wins season. I'll take it. Where do we improve from here and how , specifically how is roster looking for us next year and what about OSU? can M take them out in Ann arbor next year ??
