Uh, you saw how Burrow played in 2018 right? One of these sets of stats is Joe Burrow's first season as a starter in 2018, the other set is JT Barrett's much-maligned 2016 season:
233/379 passing, 61.5% completion percentage, 2555 yards, 6.7 YPA, 24 TD/7 INT, 135.3 QB rating, 27 sacks.
219/379 passing, 57.8% completion percentage, 2894 yards, 7.6 YPA, 16 TD/5 INT, 133.2 QB rating, 35 sacks.
Is either set completely better than the other? Probably not, right? Like, you could argue the first guy is better (more TD, fewer sacks, better completion percentage) or you could argue for the second guy if you love YPA...but it's not a dramatic difference.
I know you're being a bit facetious, but the Joe Burrow that has dominated this year in 2019 is not even remotely similar to what he was when he left Ohio State...nor was 2016 Ohio State's QB coaching, offensive line and receiving corps nearly as good as what LSU has this year. I'm a fan of Burrow (how could you not be?), but the idea that Burrow would have been anything close to what he is now is completely off-base.
