I think the underachieving part is true for some, but not all.
Cohen and Ekiyor played pretty well last year for the most part. Over 14 games played, Cohen had 10 games with no sacks allowed, and 2 games with just a half sack. Ekiyor only gave up 2.5 sacks over his 15 starts.
Dalcourt fits the bill as underachiever - he gave up as many (or more) pressures and sacks at the OGs did combined, in fewer games played.
when McLaughlin came in, we were immediately better across the entire line. It's a smaller sample size, but across his starts and other PT jumping in for injured players, McLaughlin surrendered ZERO sacks.
KR - agree on underachieving, although he wasn't super highly rated and was projected as an OG, so maybe he is just is what he is.
Latham - if he starts at RT a sophmore, I'd say that is on schedule for a lot of our top tier line guys.
That said, I think we've not recruited as well on the OL as we could have. We've gotten several highly rated guys, Neal, Latham, Brockenmeyer, Wills, Leatherwood since 2017 (picked that since that was when KR signed), but otherwise a lot (not all) of guys on the roster now were lower 4 star guys instead of higher 4 star guys, plus we had some misses like Quick, and T Brown.
