I'd say just the opposite.
The guy just set a franchise record, or tied a record for most points scored in consecutive games.
As in, no QB, not even Aikman, Staughbach, Romo, White, Peete, Kosar, Morton, Merideth, Rhome, Hoogeboom, Pelluer, Sweeney, Cunningham, Kitna, et al.....
Meaning the offense's trajectory, points-wise, statistically speaking, is better than it's ever been with any QB in Dallas' history.
What else can the guy do?
The issue is teams are getting better at drafting, assembling teams, and even really good teams have losing records. Today's NFL is the most competitive league I've ever seen. I mean right now, in 2022. These are all great teams. Just a difference of experience, sometimes, and comes down a lot to being a game of wit, because all these teams are talented.
I know, we aren't perfect. But we're far from sucking, too. Settle down. We'll get our Super Bowl soon enough. I'd say sometime in the Parsons/Diggs era.
