Did you see how well NE front 4 filled gaps? Each NE tackle took out 2 blockers and the edge guys were demanding a double team or TE help.
This leaves 3 linebackers + a SS absolutely FREE to do whatever the fukk they want at the line....ATL had 0 shot at a running game from the 1st drive, and short distance was going to be an uphill struggle w NE gap discipline & free runners at the line.
Other teams are better up front, Tenn and GB are pretty good w their FB utilization.
