IMO the team has both starters at Tackle, RG and center-with a chance of upgrading.
Left guard is a huge questionmark. I'm sure McGovern will be given another shot along with Matt Farniok but I doubt the team post draft doesn't add more talent to the line.
I see a few guards being mocked at #24, and maybe they are BPA when the pick rolls around but I just don't see the urge to take a guard in the first unless they are of the Zach Martin plug and play and get PB/possible All-Pro level returns.
Obviously the Cowboys did well doing that in the early 2010's, but all we got to show for it is a few division wins and two playoff wins. So, clearly it's not the blame of the OLine for the failures of this team, but there's only so much a stud offensive line can do when you have a poor defense or inconsistent offensive play. So, if there's a close in talent more impact position there I wonder if it would be best to pass on a Zion and try for a Salyer in round 2 or Goedeke/Hayes in round 3(possibly).
I wouldn't double dip at OL unless this was a dead obvious instant upgrade with AP level potential.
Round 1 I'd rather go WR(bleh)/DL/LB then day 2 look at OG prospects. Not a huge fan of Raimann or Smith considering how raw they seem to be and the way this team forces itself to use the draft for instant production.
If going for a project rather try day 2 or 3 for guys like Petit-Frere or Walker or Burford for OTs that need work but have traits that can be developed.
And yes, I'm going off draft profiles and limited clips of some of the above names.
