If Notre Dame is truly a playoff contender, they shouldn't lose and won't lose to a VT team that is down their starting QB, best pass rusher, replacing 2 first round picks on defense, and the best team they've played is Duke. Yeah, Bud Foster is a good DC, but the players are the ones have to go make the plays.
I'm kinda tired of hearing about the "hostile environment" thing. The staff has at least tried to get this team ready for situations like this coming Saturday by putting them in uncomfortable positions in off season workouts/practices. They also have a decent amount of experience now in playing in these kind games: FSU 2014, Clemson 2015, Miami 2017. So, if not now, then when? But, again, if Notre Dame is TRULY a playoff contender, then they will take care of business on Saturday. Alabama would beat Tech by 5 touchdowns in Tech's stadium, OSU would beat Tech in their stadium, Georgia would beat Tech in their stadium, LSU would beat Tech in their stadium; if Notre Dame wants to be talked about among those teams, then get the job done.
