Overall, I don't think that the Hawks are tackling as well this year as they have in the past few years. They still tackle pretty well (better then most other teams), but we are certainly seeing more missed tackles then we are used to.
Part of it, I'm sure, is losing Angerer/Edds. Angerer was a tackling machine. This years LB's are doing well, but they really can't compare to Angerer yet. I also think that, because of the inexperience of the LB's, we are seeing more one-on-one tackling (thus creating more chances for missed tackles).
It also seems like Sash is trying to kill someone out there. Whether he is trying to make highlight reels, or just doing what he thinks he is supposed to be doing, he is definitely bringing the pain. Unfortunately, he doesn't seem to be wrapping up - just chopping.
I'm quite sure that the coaches are working on it. I'm hoping that it is a matter of the paleyrs learning to play together, and things will get better as the season progresses. Honestly, I think they are getting better. It may have stood out more against Michigan, but DR has been damn good at making people miss.
