I dunno. Much of this is subjective and I don't see an easy way to pull data, but OP's comment rattled off about 10 names. Compare that to this list...

And it's easy to get to 15 names of players that are making a definite impact in the NFL. And, that doesn't even account for the fact that half of the names OP listed (Floyd, Watt, T'eo, Walls and Allen) all passing through the NFL like a bad taco.
It's legitimate to say that Weis left better players at WR. Beyond that? 🤷♂️
Take away WR (and possibly QB) and I'd easily prefer every other position group in '22 to '12.
