I wouldn't mind seeing this team start blitzing, even at the frequency Gregg Williams had the Saints blitzing.
Fact of the matter is, rushing 4 and dropping back 7:
They can't cover/still give up huge plays
They can't get consistent pressure.
The way this team plays coverage, it's almost as if they only have 5 or 6 men back there. Time to start sending Hightower in.
