I think the problem is most teams, rightfully so, live by Jimmy Johnson's quote, "It used to be a quarterback-driven league. Now that’s the only thing", so they reach and chase. The important thing is to identify the right QB.
You recently posted the Bill Walsh theory on finding a QB. Breaking down what Walsh said by category we have.
Instincts, mental and emotional make up, how they throw, arm strength, ability to throw any route, quick delivery, touch, ability to read a defense, ability to work through a progression, mobility, ability to play through injuries and ability to make plays under pressure in crunch time AKA clutch.
I would add to Walsh's list leadership qualities and accuracy.
How do you quantify these and how would you rank them?
I think the problem is many teams rank ability to throw every pass, arm strength and delivery mechanics too high and they don't look at the mental aspects of the game enough. Montana, Young and especially Brees don't have cannon arms. Phillip Rivers has a throwing motion that looks like he's short arming the ball at times. Chad Pennington had a noodle arm and if not for injuries and getting stuck with the Jets I think he might have been capable of being a HOFer.
You look at some of the picks in the first round and they were all about the arm and ability to make every throw. Carson Palmer, Bryon Leftwich, David Carr, JP Losman, Kyle Boller, Jason Campbell, Alex Smith, Vince Young, Jay Cutler, JaMarcus Russell, Josh Freeman, Sam Bradford, Jake Locker, Christian Ponder, Blaine Gabbert,
The outliers to that are Matt Leinart, Brady Quinn, Mark Sanchez, Tim Tebow and Bradon Weeden. With the exception of Weeden they were all overrated because of the successful program they came from. Weeden it the Browns effect of being clueless.
Some of the younger guys like Geno Smith, EJ Manual, Ryan Tannehill it's haviing the arm and mobility.
Looking at this year's potential first rounders of Bridgewater, Mariota, Manziel, Carr, Mettenberger and Hundley. I would only take Bridgewater and Carr in the first.
Maiota will be a first rounder because he has a big arm and is moble. I don't think his accuracy is good enough nor his decision making.
Manziel is exciting and has a big arm. He may be semi successful in a Jay Cutler way but will never lead a team to a championship and is not a leader.
Carr is very accurate, by all accounts a good leader and while not in the class of Manziel or Maiota athletically he is moble.
Mettenberger he has the size and arm teams want and couple that with the big school he'll get over drafted. He could turn out to be a decent QB if you can sit him for a year or two but teams don't do that these days.
Hundley has the arm and highlight film of down the field throws to excite teams. I don't see him being able to read the short to intermediate routes to move the chains.
