Lamar's pairing with Greg Roman is fantastic. Jackson was league MVP last year. He passed for over 3000 yards and 36 TDs. Referring to him (and also Kyler Murray) as a running back is not right. The immediate impact of having Lamar at QB is undeniable. Scoring 20 points on the SB favorites really just indicates that the Ravens are not the Super Bowl favorites. I don't think it's an indicator that a Jackson-led team won't make the playoffs or that the era is over. The longevity, long-term success, and success at the highest levels of running quarterbacks has not always been there.
By contrast, the Bills had decided to draft a project, but passing quarterback. It's taken a couple years, but Allen's improvement and on-the-field play this year has exceeded Jackson's improvement and play. Hopefully that trend continues for years to come.
