I finally watched the first 20 minutes of the John Doe video.
Didn't actually think the language was that bad. I've heard infinitely worse, over coffee, at work, at an S&P 500 bank.
Acknowledging that it was lowlights, it was brutal. Nobody playing QB at Alabama should have that many mistakes. I understand now both why Ridley was openly showing frustration, and the rumors of near-mutiny in the WR room, especially as the 2017 season went on.
The main takeaway is that a QB can make a mistake without throwing an interception. We're forever hearing about 17 touchdowns / 1 interception. We hear nothing about the childishly open, yet missed, receivers. We hear nothing about the passes that 5* receivers dug out of the ground, or reached high, low, behind or in front, to make a circus catch that should have gone for many yards more, maybe even a TD.
Like a Roman Catholic's sins, a QBs mistakes are of both commission and omission. Jalen makes very few mistakes of commission, and that goes a long way against 125 of the 135 or so FBS teams. Mistakes of omission? An altogether different story, and especially telling against an elite defense.
I expect Tua to make marginally more of the commission variety, and far fewer of the omission type. Net, I expect fewer mistakes out of Tua than Jalen.
