Shit, you and I just aren't seeing eye to eye on football this week. I'm probably just still pissed off by a big lumbering Ravens defense trashing my Pats. And I'd certainly like a pass rusher if we could get one but I'm not yet sold on Margus Hunt and Ansah and anyone else that's likely to be around at 29.
Do you really think the Ravens' D is "big lumbering?" Besides, I thought they shut down the Pats more because they were physical with the Patriots receivers at the LOS rather than because of anything their front seven did.
As to defending the outside run belichick appears to be ok with using Spikes/Hightower/Mayo and I thought they were ok against the run. Perhaps you could change that--I guess you could use Hightower more in the Ninkovich role and bring in a guy like Jelani Jenkins.
I wouldn't make major changes in this regard; I'm just pointing out that not only does an unathletic space-eating DT not help the pass D, it doesn't even help the run D in the situations they probably struggled most.
