There are many advantages of being in a major conference. The TV money is usually listed at the top. Don’t forget the backing of that major conference when it comes to shoehorning a team into a bowl.
Plenty of mid-majors were bowl eligible. Some with better records than a bunch of 6-6 teams from major conferences that had more eligible teams than tie-in bowls.
Pitt was among those in the 6-6 mediocrity. Still, they get to have one more game. The seniors get one more chance to notch a victory. The coaches get to have more practices and start preparing even more underclassmen for 2015.
