I agree with you regarding Dr. Collins. I understand he is a "recovered atheist." :^)
I suppose other trustworthy "outspoken Christians" who have been scientists would include such notables as Gregor Mendel, several Jesuit astronomers after which 12 of the craters of the Moon have been named, plus Isaac Newton, and -- in his strange way -- Albert Einstein; and the list goes on....
Dr. Collins is a demonstration that it's possible to completely accept God and the Savior, and accept evolution at the same time. My biggest argument is with people who will not accept that such a choice is an option.
The evolution battle has more similarities with the innumerable doctrinal arguments between the various denominations going back as far as the 1st century, than it has with any kind of scientific, or even philosophical debate.
