Its not that Romo built up this legendary status. Its moreso that non-biased fans appreciated Romo back then and are forced to defend him now bc of sensitive Dak stans. Op was about Dak and the Pro Bowl, yet by the 3rd post, a Dak stan brings up (disses) Romo.
Dak fans defense mechanism is always to diss past and current QBs to make their boy wonder look better.
My main point is that as much as some love and appreciate Romo now, he wouldn't have even been the Cowboys QB for as long as he was, if Jerry just listened to some Cowboys fans who wanted Romo gone. It was because of the Cowboys sticking with Romo that he developed into the great QB that he was and how we had good seasons with him.
Very similar things are used to bring down Dak now. If Dak isn't the QB, then the Cowboys will eventually have to move on. But, he could still develop into a seasoned QB that a team can win with, whether that he with the Cowboys or another team.
I'll admit that Dak Supporters will mention Romo and other QBs in defense of Dak. But, it also happens the other way around, where those who doubt Dak, will mention other QBs to elevate them and diminish Dak.
