As far as players on the roster by year group, let's wait till we see who really plays. I think the roster will stabilize after the ND game. But looking at the 66 positions 2 or 3 deep on the O, D, ST here's the breakdown:
Fr 16
rFr 5
So 7
rSo 5
Jr 3
rJr 12
Sr 3
rSr 15
So that's a lot of Fr. Will they play? Let's wait and see. But here is the year breakdown:
Year; # roster; Class size; % roster
2015; 16 ; 25 ; 64%
2014; 12 ; 21 ; 57%
2013; 8 ; 14 ; 57%
2012; 15 ; 17 ; 88%
2011; 15 ; 22 ; 68%
Now that 64% is a pretty good indicator of how good the Fr Class is perceived to be. That high a % surprises me. If more % 2015 players are on the roster than older 2014 and 2013! I'd expect 2012 to be the highest and some of the 2011 to have left after 4 or even 3 years.
