@Justneedme81, There are 13 of what we'd call contributors: starters or back-ups that have played a significant role this past season. It's a total of 25 when you consider graduation, etc. It's not new—as well all know too well—and the departures of the past rival these numbers.
Just as a comparative note and this is from last season which included both (and I"m sure I've missed someone, or two, along the way.
Sims and Foster weren't starters but they did spell the starters quite a bit. There's two.
In the defensive backfield we're looking at Fitz, Averett, Wallace, Brown, and Harrison. In the front seven we saw Evans, Frazier, SHD, and Payne leave. Now were are at 11.
On offense, we saw Ridley, Bozeman, and Scarbrough leave. Special teams was JK Scott.
Now we're at a 15.
There were 16 major contributors who left after 2016 along with three quarterbacks. There's a year with 19.
A brief glance at 2015 and I caught 15 more.
What's the difference in this season and the last couple of seasons? (Other than the worst loss of Saban's career at Bama?)
