Yes, Dak was an interception leader in 2022. No doubt. Numbers don't lie, if you're talking just the total number of interceptions.
But let's check other years, shall we?
2021. Dak had 10 interceptions with, in round numbers, 600 attempts. Matthew Stafford had 17. Justin Hebert, with only 72 more attempts, had 15. Derek Carr, with only 26 more attempts, had 14 interceptions.
But those quarterbacks weren't called an "interception leader".
Dak had a bad year, interception-wise, last year, with an int rate of 3.8%. But the four years before that his int rate was less than half that, with rates of between 1.5 and 1.8. Saying Dak is an interception leader is a textbook definition of cherry-picking stats, to this point in his career, anyway. Maybe that is the "real" Dak, but more seasons like this last one has to happen to prove that.
