I believe they can be, because Eberflus screams “guy who can lose the building in a heartbeat” and the talent level is low enough that they are capable of looking bad against any level of competition, even the Packers.
And we already know the season rides on Fields taking a leap. If that does not happen, this team is going to struggle, if he regresses (entirely possible with a shellshocked qb) this team will be worse than last year.
