The exception would be CB. And I can't even imagine them using a 1st round pick on a CB especially this year. They are loaded to the gills with starting quality CBs.
Sure, they absolutely should consider NT (I mentioned DLine as worthy of 1st round picks).
But, you can get a big run stuffing NT pretty inexpensively if you only want a 2 down NT.
It's good edge rushers that are the premium. Not NTs.
