I don’t see that it’s one simple thing.
I think some of of it is their bread and butter stuff being figured out in the film room over a couple of years and Buck can’t or won’t adjust well enough.
The OL taking a step back, especially before they put Randolph in.
Also, Zach did in fact play like complete trash to start this season. He’s improving but to me his game has still been just average.
Those factors, plus some key injuries.
At this point I feel like the offence is equal to what they were at the end of last year honestly. Their last really great game was last years BB.
