By almost every metric OL picks early in the draft have the highest success rate. It’s the only position group picked in the first round that consistently sees over 50% of players getting second contracts with the team that drafted them. All pro and pro bowl rates are typically right up towards the top with first round OL picks. I think only RB is higher but that’s a position where you really only see elite level guys selected.
Take that info for whatever it’s worth. Some people will say it’s easy to find OL prospects so you shouldn’t use a first rounder on them for that reason. Other would say OL is a great target for a team like the cowboys picking towards the end of the first round consistently because they can hit on those picks pretty consistently and avoid the day one busts.
I would submit that the Cowboys have an ability beyond most others when it comes to evaluating top O-line talent.
The majority of NFL teams have an average draft position from slightly to far higher than the Cowboys. Therefore, their O-linemen should be at least as successful.
The earlier in the draft....?
Actually, Tyron Smith is the only Cowboys lineman drafted in the top 10. He was #9 . Martin was #16 overall, Tyler was #24 and Frederick #31.
Since 2000, there have been 25 tackles drafted higher than Tyron, 18 guards drafted higher than Zack, 14 centers drafted higher than Fredericks, and 106 OL drafted higher than Tyler.
Two of the 25 tackles drafted higher than Tyron has more Pro Bowls, no guard drafted higher than Zack has more Pro Bowls, three centers drafted higher than Fredericks have more Pro Bowls than his shortened career, 16 of the 106 OL drafted higher than Tyler Smith made the Pro Bowl within their first two seasons.
These are the results that should belong to top 5 picks but the Cowboys ran the table with an average of 20th overall pick.
That is an average of the 20th pick in each of those drafts.
