5 huge observations from Louisville football's gut-wrenching OT loss to Virginia

2. Louisville's biggest flaw continues to struggle

The Cardinals are wasting one of the best running back rooms in college football. Jeff Brohm isn't at fault for not giving the Cardinals' star backs the ball, because when he does, the offensive line can't block for them. Louisville's offensive line continues to struggle, and the fans are beginning to realize that this team will have to rely heavily on Miller Moss and its passing attack.

Isaac Brown was one of the biggest stars in college football entering the season, but through five games, this offensive line is spoiling what should be another historic season. Brown and Duke Watson are one of the best running back duos in college football, despite what their numbers say. The fact is, this offensive line is one of the worst lines in college football and in the Power Four.

Louisville had 27 carries for 56 rushing yards. If Louisville wants to make a run in the ACC and prove they are a real contender for this conference, this rushing attack has to be better, and it starts with the offensive line. Brown has no gap to run through, and when he gets the ball, he is immediately hit. The Cards' offensive line has to be better if they want to shock Miami and make some noise in the ACC.
