I do think all the information that comes from the combine matter. The interviews being the obvious one to require a physical presence. I do think that the majority of how a GM receives information and decides on it, comes from film.
Let's just take N'Keal Harry for example. Everywhere, including the schools website has him listed as 6'4". He measured in just over 6'2. Metcalf, who's being described as a physical freak benched pressed 225 - 27 times. So did Harry.
This is information that while may not override film - is still important to any GM.
