And we're done. Another myth debunked.
You neglect to mention the "source" for that data is a Google document linked through Reddit. LMAO. The article author doesn't even know the dude. He refers to him as "Some fine soul."
Here's what your post claims are the numbers and rates for Nebraska, which are all wrong:
[SIZE=13.3333px]Nebraska[/SIZE]
[SIZE=13.3333px]2014 Signed 24 - 04 (17%)[/SIZE]
[SIZE=13.3333px]2013 Signed 25 - 07 (28%)[/SIZE]
[SIZE=13.3333px]2012 Signed 17 - 04 (24%)[/SIZE]
[SIZE=13.3333px]2011 Signed 19 - 06 (32%)[/SIZE]
...
And here are the actual numbers, with the actual percentages, with the names of the actual players who are gone:
2014 Signed 24 - 06 (25%): Harrison, Irons, Stewart, Tolbert, Walton, Wills
2013 Signed 25 - 10 (40%): Dixon, Gladney, Gregory, Hart, Love, Martinez, Miller, Mixon, Stanton, Suttles.
2012 Signed 17 - 7 (41%): Afalava, Alexander, Anderson, Brown, Curry, Moss, Seisay*
2011 Signed 20 - 11 (55%): Abdullah, Bondi, Carter, Green, Klachko, Moore, Peat, Pirman, Santos, Stafford, Starling,
So all four years of the data I checked was wrong 100% of the time. I'll go out on a limb here and say the rest of it is unreliable too.
