Today was the first day we were able to see a single rep featuring both an offensive and defensive player. Otherwise, it's just individual position drills, which aren't the kind of drills you can learn much from.
Based on what I've seen, here's how I'd map out the offensive and defensive lines, first and second unit:
OL, starters: left tackle Javon Foster, left guard Xavier Delgado center Mike Maietti, right guard Case Cook, right tackle Hyrin White
2nd team: LT Zeke Powell, LG Luke Griffin, C Drake Heismeyer, RG EJ Ndoma-Ogar, RT Connor Wood
I'd say the most competitive battles are right tackle and left guard.
As for the D-line, things are more fluid here. The top ends look like Isaiah McGuire, Trajan Jeffcoat, Chris Turner and Jatorian Hansford
At tackle, some combination of Darius Robinson, Akial Byers and Kobie Whiteside will be the two starters. Mekhi Wingo, the freshman from De Smet, got some time with the 2s today. Drinkwitz said he "absolutely has a chance (to play this year). He plays with the right kind of chip on his shoulder, leverage, got great speed. He's making plays. He's flashing."
