Lol... this is funny. Moving is what the offensive line is supposed to do. But we are going backwards.
I think you are totally wrong. Cam Jurgens not included, just look at the size, shape, and condition of NU's offensive linemen over the last 5 years. Cam was the one elite athlete for a big guy, with explosiveness, power, athleticism, and outstanding wheels for a Center. He's already proving that at the next level.
Just the total change in nutrition, the likely monitoring of a useful calorie index, and finally having a serious, modern-day S & C coach will, by default improve this group of linemen. We all know there is a serious talent deficit to be an average to the above offensive line in the BIG.
The return of Nouili, and the potential to pick up 2-3 guys from the JUCOs or portal could do wonders for the overall look of the OL.
Now, if NU strikes out through the JUCOs or the portal then this group will be limited to the new program of nutrition and S & C staff. You should never underestimate how much improvement a player or entire unit can gain with a change to a serious training regime by someone who is being paid and expected to improve them noticeably.
It's likely that physical contact and aggressiveness level will be on display, and expected in order to secure a starting job. Penciling in guys to start along the OL when they are doing a subpar job in practice could be a thing of the past.
As an NU fan, I'm not looking for giant improvement. I'm interested in noticeable improvement. The objective should be to elevate the overall starting unit to be an average BIG line.
This is a coaching staff that has more than one current or previous Offensive Line coach, so I don't suspect Raiola will be on an island all by himself trying to improve the OL.
You may be surprised at the level of improvement of some of the returnees. But going backwards? No way.
