Most NFL teams with few exceptions hang on to their Franchise QB’s who have had a fairly consistent playoff contender and with respectable passing statistics with some success. Just because you haven’t won a championship doesn’t mean your QB isn’t enough to build around .
Obviously not all Franchise QB’s are Elite but unfortunately there simply isn’t enough Elite QB’s to go around to 32 teams with usually only a handful at any given time.
The fact we have a top10 caliber non Elite QB by NFL standards especially with consistent playoff appearances would generally be enough to stay the course despite whatever shortcomings, frustrations and criticism.
That doesn’t mean we can’t continue looking in the draft for a strong backup and potential heir apparent especially as our Franchise QB ages into his 30’s.
The Cowboys are doing what most teams in the NFL have to do. Build around a less than Elite HOF caliber QB as best they can. Even those few Elite QB’s in the league is tough to build a championship team around.
There’s no guarantee either way. And I’d be looking more to the supporting cast and other contributing factors like the coaching staffs, front office continuity , team culture along with success in draft to address the other positional weaknesses but generally you’d stay the course with a QB like Prescott’s level of success.
