It's simple plays that doom this team week in and week out. Yes, the defense is horrible - but they've had a ton of stops that end up turning a stalled drive into points or a hold to 3, that turns into 7.
Defense stops them twice on 3rd down - penalties extend the drive and lead to scores.
Offense gets a first down and holding penalty negates it and stalls out drive.
The Williams fumble - if Hurts forward progress was stopped, his sure as heck was
It just seems to be the case over and over, every week.
Is it the coaching....I doubt it, because it's been a problem for years
Is it the players....maybe, but some go on to other teams and don't have the same issues
Is it ref bias....maybe sometimes, but every team probably argues the same. However, I doubt Arizona plays mostly penalty free football most weeks.
I'd love to take a deeper dive into the actual point differences based on the calls and when they happen. Maybe playing mistake free football is the difference in good teams vs bad teams....but I doubt it. Since the Bengals, Jets, Browns, Raiders, Falcons and Panthers are all in the bottom 12 in penalties called against them this season. I really think it's when the calls are made that make the difference.
