How many times were they breaking in replacements for their QB, top 2 RB, best 2 WR, and best O-lineman?
2008 (jpw, coffee, grant, mccoy, andre smith)
2011 (gmac, ingram, julio, carpenter)
2015 (sims, cooper, white, yeldon, arie k)
2018 (hurts (kinda), jacobs, harris, scarbo, ridley, foster, bozeman, warmack)
2020 (tua, jeudy, ruggs, wills)
those aren't only people lost those years, just off top of my head. other big time players were lost in some of those years for sure, especially d players on the 08-15 years.
those years resulted in:
08 - undefeated regular season, lost in seccg and bowl
11 - national title
15 - national title
18 - undefeated reg season sec champs, lost in cfp final
20 - undefeated national champs
