But Bama has at least 13 guys with some variation of an analyst/intern/assistant type role that are listed as support staff, not among the coaching staff.
According to ND's media guide, roughly 3 such comparisons might be able to claim some comparability to Bama's situation (Ernest Jones, Tim McDonnell, and Dave Peoloquin). But I am pretty sure that Tim and Dave are pretty involved in the recruiting efforts also. So it's hard to say that's even completely comparable.
Most of these schools have pretty informative media guides that at least hint at who is hired in the program and a description of their responsibilities. Looking at most of the major elite programs, most don't have near the number of research/support staff that Bama lists on its roster.
20+ employees who are solely dedicated to breaking down film would seem like a pretty solid number. Does that mean an "army"? I don't know. But it's certainly materially more than you can find with any other program. I think the Texas article originally linked exaggerated Bama's number, though, which is what I based my original comment on. I think it's more like 12-15, still considerably more than other elite programs, however.
