This was a very interesting interview. He was talking about how the most important aspects in this oline system were:
1. Athleticism
2. Time in the system (Takes a while to learn)
Mentioned how the Broncos back in the day could get a lot of starters that would spend a couple years as late picks or undrafted on the practice squad and then after a year or two learning it they’d become starters. Said the Packers have done some of that as well. Mentioned Patrick and Runyan as examples. Seemed pretty high on the scheme.
If this is all correct makes sense what Poles did. Draft a bunch of young athletic guys and let them develop. (The Bills guard fits this profile too). If you don’t need to spend a shit ton of draft capital on lineman and develop them over time that’d be great.
(And the reason he feels better about the line was the vet signings. He hasn’t actually watched them at camp. He just knew they were professional players)
