Advanced stats are useful tools but they are not the end all, same as combine results aren't. It's like what Greg Cossell said when asked about how impressed he was with Clowney's pro day, "Clowney is a very athletic guy, why are we surprised that he did athletic things without pads on?". The film also doesn't tell you about a player's psyche.
But you've got to take so many things into account. What kind of system did the player play in, what kind of players did he play with, what kind of players did he play against? Those are questions that do not show up in advanced stats, and in a lot of cases are overlooked on film.
All levels go together. You need the eyeball test, advanced stats, and the various combine drills to help evaluate. But in a lot of cases, if the combine or advanced stats don't match up with the eyeball test, I'd probably go with the eyeball test
