Granted that I'm a Cowboys bandwagon fan - I was allowed to stay up late to watch my first SB when they beat the Broncos in 1977 - but as you can see, it's been a long ride. So much for the inference you garnered of my football accumen by reading 2 posts.
I think it's fair to say that the Cowboys fans have held more promise to at least make the playoffs over the past 10 years than do either the Raiders or Browns fans (sans the delusional ones, of course). Perhaps that's the problem with us Cowboys fans - we're not willing to admit the delusion that every September brings. I've made my peace with that issue and have relegated the Cowboys to the realm of Never Contenders until something significantly changes at the top.
Jerry isn't the answer, though his ego will prevent him from selling to a more competent owner. Garrett is not the answer, nor will he ever likely be. Romo has enough empirical evidence to prove that he is not the answer. Hell, at least Danny White took the Cowboys to playoff games and holds a lifetime 5-5 playoff record. Romo could only aspire to those levels of mediocrity (and Romo can't punt either).
I guess that's where fans of the Cowboys (or Patriots, or Steelers, or Giants) differ from Browns fans - there is an expectation of winning every year, not building for the future.
