CB, S, DT are clearly are top draft priorities, where we certainly need a future starter at both Tackle and Linebacker. There is strong depth at both corner and tackle, but those are high valued positions and are usually over drafted due to demand. Think we can address linebacker even on day 3, but it will depend on how our board falls in the earlier rounds. We know the front office doesn't value the two down NT, my expectation, that doesn't get filled until day 3.
I'd like to see the opinion of the two-down NT change, or Dallas even seek a player there who can go three downs (someone like McNeill). Truth is, we've seen teams like Philly, Washington and New York play good defense at least in part because they've had two quality DTs.
Washington had two first-round DTs starting (Payne, Allen). The Giants had a second (Tomlinson, pick 55) and an early first (Williams) starting. Philly started a first-rounder (Cox) and a third-rounder (Hargrave. pick 89). During their Super Bowl season, the Eagles traded for Timmy Jernigan, a second-rounder (48th overall). That does not even include the first-rounders at DE.
Until we get serious about investing resources into DT, we are not very likely to get much better. The highest pick we've used on the position since 2005 was the 58th pick on Hill in 2019, and that was questionable since Hill was not even a full-time starter at a smaller school.
We can continue to throw all the blame on the coordinators (and they've deserved a share of it), but teams with good defenses understands that you've got to be able to hold and collapse the middle to succeed on that side of the ball.
