I feel like it is often times simply dishonest, bordering on lying, and it's a shame to see some posters who for years have been at least honest in their arguments. Same thing with the 2020 salary cap "reset" line of reasoning, but that a different topic...just same type of bizarre and dishonest reasoning about cap allotment, twisting into pretzels to explain the reasoning.
Yes, we always have exceptions; just because something is generally true and reliable doesn't mean it is true every single time or reliable every single time. I'm going to buy the most reliable car from the brand with the most reliability; sometimes, a car from that brand breaks down and performs worse than a car from a less reliable brand. On your next car are you going to buy from the less reliable brand? Basically the argument, translated to football, is that we really don't "need" an elite quarterback because, a few times in recent years, we've seen a non-elite quarterback raise the Lombardi trophy.
