I’ve read that it was Gene Smalley who came up with the blood ban and maintained it over the decades.
Wasn't blood transfusion banned back in the 1950s? Was Smalley at Bethel then? Was he even an adult then? Since when have underlings set policy/doctrine? The organizational model has, since JFR, always been from the top down, from the anointed rulers to the non-anointed other sheep flunkies, not any other way. What uninformed source were you reading?
Smalley has, however, been the point man in defending the issue, apparently supposing that Jehovah would never have guided his people into such an egregious doctrinal/practical error that has caused the death of so many.
Franz was preferable to Rutherford
Isn't that a bit like preferring simple imprisonment over imprisonment with daily floggings?
