I get that but ND has some real no brainers at OT. Lugg is going to own one of the OT spots in 2018. Eichenberg or Kraemer will own the other as they audition for it this year. And as you mentioned yesterday, the '18 OL class (for ND at least) is sub par even if NPF jumps aboard. 2019 is a year of plenty at true OT's and early returns say ND is going to rake.
Even though Hainsey was the starting LT at IMG for 2 years the subplot to his recruiting story was always he was going inside, even with the services. If he is as good as they say and you have the other spots locked down with specific players with the proper physical skill set, let him be the QB and run the line. I see him at center and a multi year captain.
