On the other side of the coin, apparently the ILB's in competition for roster spots have not shown particularly well.

McCarthy summed up the issue as follows:
“There’s too much thinking going on, and that’s understandable,” McCarthy said. “Particularly today was a very challenging installation for our defense, particularly the inside linebackers, just their volume of responsibility and communication. You’ll probably see a little more of that hopefully as the week comes to a conclusion. They need to settle in and start playing.”
This is an occupational hazard at the position, and especially in the Capers defense. The issue is compounded by the fact that the guys competing are the rookie Ryan and the OLB conversions who have little experience (or shall we say no game experience) at the position.
Cohen reported on Ryan, a pretty smart and experienced major college player:
"Ryan, a rookie from Michigan drafted by the Packers in the fourth round, acknowledged the difficulty of each new installation and said mistakes are bound to happen. He has caught himself overthinking, allowing concepts to get 'jumbled around' in his head, and the result is even more of an emphasis on film study to make the proper adjustments. 'There’s going to be stuff that I need to improve in,' Ryan said. 'That’s just a matter of getting in your playbook, getting the film, asking the older guys, stuff that you need to do. That’s what I’m doing right now.'
Which "older guys", one wonders? Barrington and Matthews each have a 1/2 season under there belts.
On a related note, reports indicate Matthews has been working mostly in base defense, flipping the script from last season where he did most of his inside work in nickel. This could be a function of the fact Matthews had little or no previous work in that role and they want to explore the depth of Matthews' versatility and what kind of chemistry evolves out of it. Or it could be the plan, in which case somebody will have to step up to a 65% snap count.
Perhaps some de-installation will eventually be in order, in keeping with the McCarthy defensive theme for this year: less scheme, more pre-snap adjustments.
