Lamar Jackson is a breath of fresh air and a remarkable talent. However, the career arc of such quarterbacks needs to get beyond the stage where opposing coordinators now have tape on you. Also, footballstudyhall (or it might be footballoutsiders) has a talent chart, and Louisville is barely above average in talent. Sooner or later, everyone on the team will need to contribute, and outside of the guys we have already seen, they don't have much.
I think Clemson has a bit more talent and are a bit more immune to the media exposure. Self-congratulation is a destructive emotion for a team that must now prepare for a deadly serious opponent.
