Andrew Luck's father played QB in the NFL and he's the AD of West Virginia, that's pedigree - you can't nurture a future NFL Qb in a home better than that. Add that to the facts that he's a damn good athlete in his own right and produced at a very high level in college and it's no wonder why everyone thinks he's the clear number one pick. It doesn't have anything to do with the color of his skin.
Griffin was better than Luck in every statistical category last year, every single one. Griffin was more accurate by 1% point (not significant but still), threw for 700 more yards, ran for 550 more yards, threw 4 less INTs, had a full 2 yards per attempt higher than Luck (10.7 to 8.7), both had similar strength of schedule so that wasn't a factor.
And of course Griffin destroyed everyone at the combine so the physical factor was in his court as well.
I guarantee you if all of his stats last year and measurables from the combine were instead put on a white body instead of a black one, he would have been #1 pick. No doubt in my mind.
