I actually liked some of the Panthers talent (as role players) on offense that year ... BUT:
1) The best receiving success rate of any of their WRs was #3 receiver Curtis Samuel at 53.6% (84th in the NFL in 2020). That offense really, really needed a true #1 guy that could reel in a steady-Eddie 60-something % success rate.
2) They got zip out of the tight end position - their leading TE caught 20 balls for 145 yards on the season.
