I did not see an actual answer so I am going to try and answer the OP question.
1. We can technically sign up to 35 without over signing, grey shirting, or anything like that.
2. We will likely only have roster spots for 32 because of the 85 player scholarship limit
So how you say...
1. We had 20 in the 2013 class and 5 of those were EEs. EEs are allowed to count towards the previous years class. This means 2013 we had 15 official players sign. This left 10 scholarships that could be used for the next years EEs. BTW, 10 is the max you can do this for. Fast forward to this year. If we have 10 EEs, they would all be counted towards the 2013 signings. This would leave 25 scholarships for 2014. That would be 35.
2. If you look at the current 2013 roster, we have up to 30 seniors that will be gone and 2 underclassmen (Tiny and AJ) that may go pro. This would be 32 spots before the limit is reached. This number could grow if players transfer (Peterman) or leave for what ever reason.
Hypothetically, say we are able to sign 35 for the 2014 class. Where would that leave us for 2015? Well, the good news would be that we loaded up on talent in 2014. The bad news is that if there is no other attrition except the graduating class, we would only have like 15 spots on the 85 man roster and there would be no EE spots for the previous year because we signed a full class. This would mean we only would have 15 scholarships to offer in 2015.
Keep in mind, the above is using the unlikely assumption that there would be no other natural attrition which we know will happen.
I hope this helps. I spent hours figuring this out and while I may not be 100%, I am about 99% correct IMHO :salute:
