OK, show the record of cowboys O line players considered really good that were not drafted in the first rd this century?
The record ain't good, dude.
Not personally attacking you, but it's clear you haven't paid attention or reviewed game tape.
Here. Let me help you and those who think like you (needing to draft only 1st round picks to find good Olinemen).
C Tyler Biadasz was drafted in the 4th Round. He made his 1st Pro Bowl this past season after barely his 3rd season in the league.
G Matt Farniok was drafted in the 7th Round. Farniok was having such a solid season at Left Guard before he tore his ACL, he teamed up between Biadasz and rookie Left Tackle Tyler Smith. All 3 were a very good triple combination securing the left side of our Oline. In only his 2nd season, Matt Farniok would have had a monster year starting at Left Guard had he not gotten injured.
RT Terence Steele was an undrafted free agent Olineman who was in his 3rd season and was absolutely dominant at Right Tackle. Had Steele not torn his ACL, he would have most likely made his 1st Pro Bowl as well.
Watch the films below and pay attention to all 3: Biadasz, Farniok and Steele. Absolute young and cheap beasts who were starting and dominating at their positions.
Cowboys vs Browns (2022): Week 2

Cowboys vs Giants: Week 3

6.4 yards per play
0 sacks allowed

Starting Week 4, that joke of an ex-Oline coach, Joe Philbin, started playing games by benching Matt Farniok for a mix between Connor McGovern (3rd Round pick) and old man Jason Peters. McGovern struggled against the Commanders and Rams. It's clear the Oline was more balanced and dominant in both the run and pass when Farniok was starting at Left Guard.
Cowboys vs Commanders: Week 4
217 yards passing
62 yards rushing
4.9 yards per play
1 sack allowed
Cowboys vs Rams (2022): Week 5
76 yards passing
163 yards rushing
4.5 yards per play
5 sacks allowed
Cowboys won 22 - 10
Aside from RG Zack Martin and rookie LT Tyler Smith being 1st round picks, plus now ex-Cowboys G Connor McGovern being a 3rd round pick, the rest of the Oline was looking very solid with mid-to-late-to-undrafted players in Biadasz, Farniok and Steele. Farniok and Steele will be healed and ready to go for the upcoming 2023 Season, so there is no need to panic and waste a 1st Round pick on another Olineman. Keep drafting them in the mid-to-late rounds...and keep developing them. It's working so far in Dallas.
