I posted this in another thread, which is based on my evaluation after they arrived:
2006 (Germano) - 2.68 (Price, Hodge, Luchsinger, Posey, McCrae, Williamson, Garrett, S. Jackson)
2007 (Germano) - 2.65 (Keller, Flading, Dunlop, Strum, Brazill, Harden, Davidson, C. Meyers)
2008 (Germano) - 2.93 (Huynh, Carlotta, Carrie, Weller, Herman, Thompson, Lewis, Futrell, Moore, Tafua)
2009 (Germano) - 2.94 (Lechner, Hughes, Fortune, Woseley, Allen, Dovell, Jones, Foster, McGrath)
2010 (Isphoding) - 2.15 (Carpenter, Cochran, Krstoff, Ingol)
2011 (Haines) - 2.59 (Russell, L. Smith, Crutcher, McQueen, Wells, Vick, Purdum, Jov. Johnson, Bass, Lucas)
2012 (Haines) - 2.86 (Gibbons, Watson, Laseak, Patterson, B. Brown, Tor. Davis, Reid)
2013 (Haines) - 3.16 (Wood, Sayles, Poling, Basham, Mangen, Cope, McLeod)
2014 (Haines) - 3.40 (Lowery, McCray, Walker, Brunson, White, Preuhs, Brunis, Nelson, Langenkamp)

Then, in different thread, the number of other offers the recruits had, by year:
2005 (Jrs/Srs in 2008-2009) - 0.40 (25 freshmen)
2006 (Jrs/Srs in 2009-2010) - 0.93 (15)
2007 (Jrs/Srs in 2010-2011) - 0.84 (19)
2008 (Jrs/Srs in 2011-2012) - 2.00 (15)
2009 (Jrs/Srs in 2012-2013) - 1.24 (17)
2010 (Jrs/Srs in 2013-2014) - 1.08 (12)
2011 (Jrs/Srs in 2014-2015) - 2.50 (22)
2012 (Jrs/Srs in 2015-2016) - 2.71 (14)
2013 (Jrs/Srs in 2016-2017) - 2.28 (18)
2014 (Jrs/Srs in 2017-2018) - 2.28 (18)
2015 (Jrs/Srs in 2018-2019) - 3.46 (13 so far)

and the percent of players from the class that were making significant contributions by their second year:
2005 - 24% 6/25 (Stuck, Morsillo, Parson, Mitchell, Hartke, J. Meyers)
2006 - 33% 5/15 (Price, McCrae, Garrett, S. Jackson, Luchsinger)
2007 - 26% 5/19 (Davidson, Brazill, Dunlop, Keller, C. Meyers)
2008 - 67% 10/15 (Carlotta, Herman, Thompson, Bussey, Moore, Payne, Lewis, Huynh, Weller, Carrie)
2009 - 24% 4/17 (McGrath, Lechner, Woseley, Jones)
2010 - 33% 4/12 (Foster, Carpenter, Kristoff, Ingol)
2011 - 41% 9/22 (Fisher, Bass, Wells, Russell, Crutcher, Purdum, J. Johnson, L.Smith, Roback)
2012 - 57% 8/14 (Gibbons, Watson, Patterson, Reid, T. Davis, W. Johnson, Laseak, B. Brown)
2013 - 56% 10/18 (Mangen, Morgan, Cope, S. Smith, Quallen, Poling, Alexander, Basham, Sayles, Wood) plus Smart and Porter have played in 4/7 games
2014 - >53% 10/19 (Lowerey, Langenkamp, Pruehs, McCray,OUellette, Brunis, Walker, White, Brunson, Nelson) plus more by next year, I would guess

All the numbers come out the same, a jump around 2008-2009, which was reflected in the teams of 2011-12, and then a dip, followed by another jump in recent years, which should be reflected in 2015-2017.
