Week 1 went largely by the book. Ranked teams dominated unranked teams, and the favored team generally won their matchups with other ranked teams. There were some exceptions, though: LSU beat Miami (although the game was actually about as close as the Vegas line and F/+ projections expected it to be), Maryland again upset Texas, and the Big Ten East had a lackluster day overall.
The Big Ten was a popular pick for the toughest conference heading into 2018, with five teams ranked in the F/+ top 12, and the same five in the preseason AP Poll's top 14.
