Some goal-line plunges on this Sunday morning as we get ready for the latest Bills fast start that will fade into oblivion (sorry for the late start today, but there are times where my body says get some sleep, and I listen. Just crashed last night) ...

Through three games this season, the Patriots' run defense (and pass defense, and total defense ...) ranks first in the league in efficiency, according to FootballOutsiders.com. That's a huge change from last season, when the Patriots finished 19th.

Largely, the personnel is the same outside of Jamie Collins. And while he's certainly made an impact, he's not responsible for all of that improvement. The biggest reason why the Patriots are much better on the ground: look inside.
