There are fewer dominant DT’s in the NFL than there are pro bowl caliber QBs or LT’s, and it’s also a position where you can give 2(or more) significant playing time. If you have the 3rd pick and Dexter Lawrence is on the board, you are significantly less likely to trade out of that pick than if you had the 3rd overall pick and had just taken Tua the year prior with SF on the line wanting to give 3 1sts to take Trey Lance.
I’m saying the scarcity of top 10 DT trades isn’t because they’re not worth it, it’s because the opportunity to trade up for a premium DT is dramatically rarer. We moved up to 9 to get Jalen Carter because Chicago didn’t trust his off the field behavior. If he were a saint, there wouldn’t be a (reasonable) draft haul conceivable that they would have let go of that player.
Now if you’re saying Mason is overvalued and he’ll be there at 12, that’s your opinion and that’s fair. But otherwise; If someone says “sure we’re listening and Mason Graham is on the board”, this is a once in a lifetime
