The reality is this. You win and lose along the LOS on both sides of the ball. GT has lacked a great OL since probably 2016, and in reality GT has always had (regardless of HC) a hard time getting top level DL talent.
If you have a solid OL the offense always looks like a well oiled machine. Same on D with a sold DL. You can see the programs who have both pieces annually. Michigan, tOSU, Alabama, Clemson, uga, etc.
Overall the team on offense at the skill positions has really good talent and speed. UofL is a good team, and the game could have gone either way.
GT has 6-7 winnable games left, and that doesn’t include UNC who GT somehow has owned during this down period. The game at Wake in 3 weeks is really going to set the table for the remainder of the season. 2-2 after 4 games gives GT real shot at 6-7 wins, a loss at Wake spells a 5-6 win season.
