I've refrained from piling in with herd on mocking your pessimism, but holy shit, man. The substance of your conclusions boils down to "things have been bad in the past," "we lost games last season we shouldn't have" and "therefore, we are doomed to eternal mediocrity." No matter the topic at hand.
You are clearly more intelligent and articulate than the ATM fan base, but your mindset is only a couple chromosomes away from "tu hasn't done shit since 2009," "lol 5-7," and "oh, the sips got a two 5-star QBs? Have fun losing to Kansas for forever!" In other words, you camp with aggie in responding to any optimism or positive data point re UT with negativity supported by history - history that in many cases is not determinative of the subject at hand.
Will history continue to rhyme? Maybe. I don't know and hope not. What I do know is I'd rather make my experience as a fan as positive and enjoyable as it can be under the circumstances, which means viewing through the lens of optimism. That UT can free itself from recent history, throw it in a river and watch it as it floats under bridges and out of sight.
