Well the current rookie contract rules haven't been around that long either. But if you look at like a Flacco, Roethlesberger, and Manning for example, they were under the old contract structure, but were still on their rookie deals on their first SB and were playing on big discounts. And a huge number of losing SB teams have had rookie contract QBs.
Now the rookie QB thing has became immensely overstated. It's really a "QB on a discounted deal" thing we're most of Brady rings that is true, Stafford, and really almost every winning SB QB except Mahomes most recent rings.
But yea, a 3rd for Judon is a lot in isolation. But in terms of sustainability, I also don't think you can call sustainability an approach where you never reach. What most people want when they look at sustainability is a draft pick and salary cap hoarding approach where you're never uncomfortable. But that's just conservative nonsense not sustainability. Poles first year was unquestionabily a tank, but the longer he goes on I'm actually optimistic he will have a sustainable approach that mixes aggressiveness and value in a symbiotic way that is sustainable and doesn't require cycles of re-tanking.
