An Elite QB is one of the rarest people on earth
Right and I could use a lot of examples of teams that have aggressively pursued this, failed, and by most counts because of this fit the description of a mess but I'll go with the top two that come to mind, the Bears and Browns.
I started watching the NFL around 1980 and in that time the best Browns QB IMO was Brian Sipe. That year out of Baker was probably the best individual year and I can see an argument he was the best Browns QB since this time, and especially since they returned as an expansion franchise, and he's considered a bust relative to the resources spent on him, at least as the Browns are concerned. I'd strongly guess that since the Browns returned as an expansion franchise they've committed more resources to the finding a franchise QB then anyone and they are no closer to finding an answer.
As for the Bears, certainly want to acknowledge they've had championship winning QB's in their history but for a franchise that started in 1920 the lack of high end caliber franchise Qb's could not possibly highlight how difficult it is to obtain one if I tried. Understand 4K passing yards is not the end all be all but you certainly expect a franchise QB to be able to do that and I'm sure most people saw the jokes going around a few weeks ago that Chicago produced a Pope before they produced a 4,000 yard passer. Last week or so this joke was reused when the oldest living person in the world passed, at 117 years old, and I saw a joke that she saw 2 world wards, rise of fall of the soviet untion, world go from horse to rockets, but she never saw a Bears QB throw for 4,000 yards.
It's hard to find one and as Steeler fans from the early 80's on know we went about 25 years between franchise QB's the last time. That was due to a massive mistake that even 12 year old me knew at the time was a horrible decision and not in hindsight, which was passing on Marino. I don't see the big not in hindsight mistake this version of the orgination is making, just a tough thing to do.
