I have no problem criticizing anyone associated with the Packers organization from the front office to coaching staff to the players - IMO that's part of being an informed and engaged fan(atic), even if the team is 3-0.
Regarding Clay a couple of things: Of course I have no idea if he is using any PEDs but what I do know is he has had a quad injury and I know the Packers keep injury information as "close to the vest" as they can. Also last year Clay had 6 sacks after the first two games, and "only" finished with 13.5 for the season - just 7.5 more in the other 13 regular season games he played (a little more than one-half a sack/game), so perhaps whatever is wrong with him happened last year after game two? j/k
One thing I do disagree on is this: the quickness required to get to the QB is the same quickness that is required to blow up running plays in the offensive backfield as Clay did to Forte. My guess is the quad injury, the tentative rush vs. Newton to control his running, and teams paying particular attention to where Clay is before every play contribute to the perception something is wrong with him.
After every game, Bob McGinn rates the Packers by position. Here is what McGinn has had to say about Matthews: Versus the Saints: McGinn relates what we already knew: Matthews had the first hard contact on Ingram at the goal line on the Saints last play. Matthews was single-blocked 23 times, double-teamed 13 times, ran stunts 6 times, and dropped into coverage 9 times. He tried to help Walden, who struggled covering TE Graham, and he had four pressures including two knockdowns.
At Carolina: The Panther's OC, "had no intentions of letting Matthews control the game against Bell. The Panthers double-teamed him on 48% of his individual rushes and limited him to three pressures. Give Bell some credit. He stayed down when Matthews tried spin moves against him." McGinn doesn't mention it but I will reiterate that it looked to me like the Packers were not "all out" rushing Newton as they would a less mobile QB.
At Chicago: McGinn says Matthews had one of his best games, registering four hurries, 3.5 knockdowns and 2.5 tackles for loss. He says Clay did about equal damage against Omiyale and Spencer. He got double-teamed on 44% of passing plays. "Despite exerting far more energy because of the nature of his position, Matthews tends to wear out blockers in the fourth quarter. On a pair of aborted counter plays, Matthews shot across the line and beat the pulling guard (Williams) to the punch, which probably demoralized Forte and coordinator Mike Martz." So according to McGinn, Matthews in three games has one sack, 11 pressures and 5.5 knockdowns.
It may surprise some fans that Matthews isn't doubled or triple teamed every passing play, but no pass rusher is - that is too predictable for the NFL. But there's little doubt Matthews has been studied by every OC, OL coach, and OL the Packers will face this season and opponents know where he is lined up every play.
