For what it's worth, I'd say the main problem is most modern 737 drivers sit with very low hour cadets in the right seat, and Boeing's training is very much focused on automatic flight. When they reach the left seat, a lot of Captains came up the same way and have done very little hand flying. Neither pilot is very confident hand flying and very few practice regularly. Thus when it goes pear-shaped, they are not ideally trained to cope. Grumpy old git. That's me.
