Quickness and speed are 2 different things. CJ is quickness, strength and technique.
He hasn't had average seasons. Sacks is a poor way to look at a pass rusher as there is high variance in most pass rushers when it comes to sacks. He has been a very consistent pressure producer even though, unlike most pass rushers, he has not benefited from complimentary rushing from the rest of the line for the most part.
You and Lamardirts need to go find Doc Brown, hop in the DeLorean and go back about 5 to 10 years so you can be happier with the AAV's.
