If you like to gamble....The most likely OL Texas rolls out, IMHO is as follows.
Soph. LT Connor Williams, 6-6/290...True Fresh. LG Patrick Hudson, 6-5/325...True Fresh. C Zach Shackelford, 6-3/290...Soph. RG Patrick Vahe, 6-3/320 and Senior Kent Perkins, 6-5/320.
Lots of potential along that OL, though from what I recall seeing previously, Perkins is still more of an OG than an OT.
But starting 2 True Frosh OLs (especially a Center) directly in front of a True Frosh QB, along with a new RB....all playing in a brand new offense.
That's a lot of opportunity for miscommunication and mistakes, especially early in the season.
You can bet ND will use veteran DTs and lots of blitzes to attack the young interior of that OL and try to rattle a young QB
