I'm not so sure.
At the college level, you can win games with one super athlete at quarterback and a team of half-decent guys surrounding him. And because of that, there are still a lot of coaches subscribing to that formula to the detriment of their QBs future employment.
The only two coaches I knew of who spent serious effort on trying to teach their athletic QBs to be just as good at passing as they were at running (Bill Stewart of WVU and Jim Tressel of Ohio State) are no longer coaching in the college ranks. If there's anyone else who's taken up that mantle, I couldn't tell you who it is.
Maybe someone else can.
I think that almost every coach tries to develop their QB into better passers. Not all of the QBs succeed in that endeavor and you will see coaches scheme around the QBs shortcomings.
NFL QBs, whether they are athletic or not, are rare. There is 119 teams and maybe 6 or 7 QBs get drafted a year. Most QBs aren't very good NFL prospects
My point was, that high school QBs that are coming through the pipeline are more and more athletic and can now throw the ball very well. More and more athletic QBs are developing at a younger and younger age. They are starting to look more and more like RG3 and Cam. There is also less and less of the traditional straight drop back pocket passer because so few teams are running an offense that caters to those QBs.
The pool of QBs that are dual threat QBs is growing and growing. The pool of QBs that are just drop back passers is shrinking and shrinking.
As far as coaches that try to teach QBs to pass just as well as run. Gus Malzhan, Larry Fedora, Dave Doeren, Kevin Sumlin (he is actually a pass first, and if you can run we will adjust type coach), and many more that run these types of offenses, want balance on offense. But sometimes players can't provide that balance so they adjust to their QB.
But I think all of them try to develop their QBs as passers as well as runners.
