No amount of sugarcoating will change how poor the 1st round went for Dallas. Frederick would've been a solid late 2nd round pick. They made a horrible trade down, only getting a 3rd rounder, and then overdrafted Frederick. We would've been better off with what NE got for their pick - several spots later - and still been able to get Frederick.
What you'll see if you watch his games against the better teams they played is a guy a guy who was physically overmatched. He's not a dominant football player by any stretch.
He's not a bad player either, but they passed on some high caliber prospects at 18, especially front 7 players. The draft isn't just about making your team better, it's about making your team better relative to the rest of the league. The "he'll start immediately" argument is nonsense. So what? That's only a testament of how pathetic the existing interior linemen were, not Frederick's ability.
Which is a shame because I believe most of the rest of the draft was solid for Dallas. I thought Philly killed it, but then they did have a top 5 pick. I thought the Commanders' draft was uneven. To me, the NYG draft was a lot like Dallas, an overdrafted OL in the 1st round, but then solid picks thereafter.
