Looking at QBR for various seasons, it shows for Ohio QBs:
2004 Ryan Hawk 16.1, Austin Everson 18.1
2005 Everson 17.6, Brandon Jones 5.7
2006 Everson 24.5, Bower 23.4
2007 Bower 29.8, Scott 25.9
2008 Jackson 51.5, Scott 41.8, Jones 24.9
2009 Scott 39.8, Jackson 22.5, Tettleton 1.6
2010 Jackson 41.4, Bates not computed
2011 Tettleton 60.5, Bates, Snyder not computed
2012 Tettleton 59.9, Vick 44.9
2013 Tettleton 55.6, Vick 52.2
2014 Sprague 29.3, Vick 61.5, Windham, 29.1
2015 Vick 50.8, Sprague 52.8, Windham 39.3
2016 Windham 55.4, Maxwell 14.7
2017 Rourke 76.6, Maxwell 36.9
These stats are, umm, interesting. If you accept them, Ohio's QBs were all pretty bad until Tettleton, but since then, Ohio's QBs have been good, in Vick, Sprague, and Windham.
They don't compute career numbers, but if I do a sort of weighted average, I get the following, from worst to best:
Brandon Jones 14.9
Ryan Hawk 16.1
Everson 20.8
Bower 28.5
Maxwell 34.3
Scott 36.9
Sprague 37.5
Jackson 45.7
Windham 52.6
Vick 54.1
Tettleton 57.6
Rourke 76.6
Another interesting thing pops out at me when you look at QBR. Some have argued that most QBs showed no improvement from year to year, but on QBR, all of them did, except for Boo Jackson. Scott and Tettleton improved a lot from their first years, but then were pretty constant. Resorting the list from above by QB:
Ryan Hawk, 2004 16.1
Everson 2004-6: 18.1, 17.6, 24.5
Jones 2005-2008: 5.7, 24.9
Bower 2006-2007: 23.4, 29.8
Scott 2007-2009: 25.9, 41.8, 39.8
Jackson 2008-2010: 51.5, 22.5, 41.4
Tettleton 2009-2013: 1.6, 60.5, 59.9, 55.6
Vick 2012-2015: 44.9, 52.2, 61.5, 50.8
Sprague 2014-15: 29.3, 52.8
Windham 2014-16: 29.1, 39.3, 55.4
Is this how people see it? Rourke at the top, with Tettleton, Vick, and Windham all about the same? Almost all the QBs showing steady improvement from year to year?
