I think the LSU roster was normal-great and I'm not sure about the lines. Bama, in the past 7-8 years, has had among the most talented rosters of all time.
but we aren't talking full rosters, we're just talking players who played significantly. and in that case, lsu 2019 was comparable to 2020 bama.
excluding qb's and defense, here are the draft results and/or projections (for projections i'm going with optimistic projections for each, and these are actual results unless noted otherwise):
lsu:
3 1st-2nd round wr (1 drafter 1st, 1 projected top 5-10 and 1 projected late 1st-early 2nd in 2020)
1 1st round rb
2 3rd rd oline
1 4th rd oline
1 7th rd te
their oline won the joe moore award for best college oline in 2019.
and for the 2020 nfl season, every
nfl eligible player from that 2019 team ended up on nfl rosters, even those undrafted, which includes another wr, te and 2 more oline.
awards for those players include the belitnikoff, unanimous aa wr, 2nd team aa oline, 3 first team all sec, 3 2nd team all sec.
bama (the are all projections for 2020):
2 1st rd wr (1 top 5-10, 1 top 15-20)
1 1st rd rb
2 2nd rd oline
1 3rd rd oline
1 5th rd oline
1 6th rd te
bama oline won same joe moore award in 2020.
future draft projections for players ineligible this draft include a top 3 rd wr, top 2 rd oline and draftable rb 4-7th (those are generous guesses if they were in this draft, could change with monster year in 2021).
awards for those players include the heisman, belitnikoff, maxwell, walter camp, hornung, ap poty, sporting news poty, sec off poty (all smith, most of these went to lsu's burrow in 2019), doak, outland, jacobs, remington, 4 unanimous aa (wr, rb, 2 oline), 4 first team all sec, 1 2nd team all sec oline.
