Cowboys fans are used to Cinderella QB stories. Romo was never supposed to be the starter for a single game, much less 10 years. Prescott was third-string arguably fourth-string at one point before rookie season. Heck, even the great Roger Staubach began his pro career as the backup to Craig Morton.
Quarterbacks historically have stretched the limits of Cowboys Nation's imagination. Franchise starters have emerged suddenly, like lightning flashes. And yes, Rush's three starts have been outstanding. He has played within himself. He has made plays when they've needed to be made. Guys around him have really stepped up.
Let's just appreciate the reality of the situation. The Cowboys have found a viable backup to Prescott. That's a good thing. No further debate is needed.
