Other than being completely wrong ...
In 2015, Ohio State took 27 commits - 12 from in state.
In 2015, Michigan took 14 commits - 3 from in state.
Pretty confident without an advanced degree in math, 15/41 isn't a majority. In fact, a significant number of these commits came from non-border states.
If you are going to make a statement of fact, at least make an honest attempt to say something factual.
My statement is pretty close for Ohio State. If you really are talking about a degree in math, you would know one year is not an adequate sample size. Lets look at 5 years for Ohio State.
2015, 27 total commits, 12 in state, 5 of them 4*
2014, 23 total commits, 9 in state, 7 of them 4*
2013, 24 total commits, 10 in state, 5 of them 4*
2012, 25 total commits, 15 in state, 9 of them 4*
2011, 24 total commits, 14 in state, 7 of them 4*
Over those same 5 years, Michigan did only get 30 in state recruits out of 102 total with 14 being 4*. So I may have generalized. If you look at these 2 programs only recruiting Michigan and Ohio, they do pull the majority of their classes. If you add in more of the Big 10 footprint the % would get even larger.
Just Ohio and Michigan, Ohio State recruited 63 out of 123. Michigan recruited 60 out of 102.
I may have made an over broad generalization, but it is still true these two schools don't have to go far to recruit where negative recruiting tactics are less likely to work. Just think how much easier it would be for these schools to pull kids from Texas, California, or SEC country when the Big 10 is considered strong.
