Whether JuCo lineman >> HS lineman is still very TBD. The JuCo lineman approach has been Adams (definite success), Crisler (bad), and the rest is very TBD. The guys that Illinois prioritized but went elsewhere (Blackstock + Wiggins), guys that seemed very likely to start if they came to Illinois, are playing very sparingly and have been a mixed bag. The portal lineman haven't been recent, but is there really that much of a difference? Badovinac was good, Jeresaty was bad, Davis was moved to DL. There's less of them, and we still have a lot to learn about Crisler (can he be average at guard? Is he healthier? Last game brought some optimism), Leys, and Schuster.
We're likely about to learn a lot about the HS line recruiting in 2024. Plenty of guys (Whitenack, Okla, Moller, Barley, and Leonard) are going into their third year and will need to push for playing time. Lots of buzz about Henderson. Both tackle spots will be open competition. Barring transfers, we could see a '24 offensive line something like this:
LT - Henderson (r-FR)
LG - Gesky (r-JR)
C - Kreutz (r-JR)
RG - Crisler (SR)
RT - Whitenack (JR)
I'm guessing the staff would REALLY want another tackle option because it would mean going into next season with two tackles who have yet to make a start. Whether that's a portal or JuCo option - someone they believe can come in and provide snaps in a swing tackle option or compete to start.
