Maybe before you make that statement and try to put too much weight on it, you should look at who those top 15 teams were first? After you do that, look at who of those 15 teams did the Packers play against and after that, what games Clay played in and how many snaps. I will do the math for you. Clay did not get sacks in 4 games against the top 15 teams in fewest sacks allowed.
