Run defense still a problem

I think people just gotta face the fact he's a 35 year old Linebacker. He defied the odds wonderfully, but the lug nuts holding the wheels on are starting to loosen.
The team is kind of at a crossroads with it's older players and not much behind them. DD, Cam, and Mathieu are all top 10 cap hits and only one is playing up to that right now on defense for various reasons. Add in that offensive players AK, Taysom, Carr and Ramczyk are also in the top 10 salaries and we have some serious money tied up in aging players that are an injury or a year older away from being ineffective. The next couple of seasons are really going to change the faces on this roster.
