think a lot of that has to do with lack of prep work by the player - the game isnt just throwing the ball... think a lot of these young guys skip they mental work aspect of development... afterall, why not, they probably didn't have to do a whole lot of it at the college level where natural talent can overcome a lot of deficits in a guys game... And a solid #2 would be poor coaching... the coaches just don't do enough in terms of developing skills & knowledge ... combine that with the first one, and its a career killer...

as for the op...
worst patriot quarterback ever? minimum 8 starts?
Christian Ponder for the Vikings? NFW I'd submit there's more to a 'worst of all time' than just stats. How about being the reason your team can't win?
Kirk Cousins today signed a one year extension. He is now under contract through 2023. 2 years with an $80M dead cap hit...for Kirk Cousins...Kirk F'n Cousins. When that extension runs out Minnesota will have paid him $154M over the course of 5 years. Don't get me wrong, I never begrudge any player what they get paid, good for him. But from an organizational standpoint his contracts single-handedly strapped the team to the point where they can't get the additional pieces to get them past being @ a .500 team. From a business standpoint investing in Kirk Cousins may well be the worst decision MN has ever made period
The Bucs can run out a list of QBs that were terrible in their organization (while having varying degrees of success elsewhere): Vinnie Testaverde, Steve DeBerg, Steve Young...
If you're going with the worst QB? It's probably Steve Spurrier. But hell, if you're going for biggest waste of a #1 draft pick (considering the talent you had at the time)? Jameis Winston is as good of an argument as Testaverde.
