I suppose that this will interest a few folks, so I'll post it.
Alabama played last year with a 116 man roster [85 scholarships and 31 walkons]. Here is the breakdown of the scholarships:
1). Saban carried 4 specialists [K,K,P,LS] and had walkon backups for each;
2). Five QBs [so do we];
3). Six and a half RBs [we carry six];
4). ten WRs [we carry eleven];
5). six and a half TEs [we carry five];
6). fifteen Olinemen [we carry 14 --- since five of these are our incoming freshmen, note the contrast for last season].
7). fourteen DLinemen [we carry eleven --- again, note the contrast];
8). eleven linebackers [we carry thirteen --- Diaco bias?, or just less confidence in our lower end quality?];
9). thirteen DBs [we carry EIGHTEEN --- which is why I've been moaning about "overstock" for a while].
The numbers for the offenses are about equal, with Saban stocking superior linemen numbers. The numbers for the defenses are not equal [Alabama 38; ND 42], yet Alabama has a significant DL numbers superiority despite less total. This is another reason that we should cut the glut on DBs entering --- elite yes, numbers, no.
What "insight" this really brings to anything I don't know. What I think that it says is that Coach was dealt a pretty lousy hand as to overall roster when he arrived [worse than I thought] and has had not only to scramble hard for repairs, but to risk somewhat unbalanced signings due to things like "three really good corners to start, but all quickly graduating leaving no one behind them". Result?: desperate over-signing of DBs/ATHs in order to hope for a miracle. I note that Coach played this bravely by going the "remarkable athlete route", which ended up producing 3 of our 4 DBs last season, albeit understandably raw.
