Justin Fields traded to the Steelers for a conditional 6th round pick

Coming out of college, Fields was a much better passer than Lamar Jackson, although raw. Because Lamar Jackson has great coaching, his coach saw what was needed for him to succeed in the NFL, so he scrapped the offense that they had in place for Flacco and in the 2019 draft, the Ravens put on a master class in building in the draft. That season, Lamar Jackson won MVP and the Ravens won the AFC North. Take from that story what you will...
Lamar is way more talented than Fields. It’s not all coaching.
