It would be nice if everything and everyone was judged solely on their merits. Unfortunately, that doesn't matter one shit in the real world of college football, or perhaps in the reality of many other areas. We don't have rainbow riding unicorns flying out of the top of the Cathedral either.
Pitt fans have to start accepting, that in college football, they are actually significant part of the equation of the program. Pitt's fan base is currently a hurdle the program has to overcome (and has successfully overcome in the past), along with other aspects of the program like facilities, administration, resources, coaching, and general football talent. The fan base can either be a positive part of the equation for the football program, or it can be a negative that simply provides another hurdle to overcome on the path to success. There is no way around the fact that for the last 100 years, and that compared to programs that the fans want Pitt to be competitive with, and even somehow believe Pitt is better than, that the fan base has most often been a hurdle not a boost.
People's negative attitudes towards the bowl games is absolutely indicative of one of the many problems with the program, and it only takes familiarity with other programs to know just how poor this fanbase can be.
