maybe they can't get the 3 and outs because they are gassed, the answer is in there somewhere and I hope the coaching staff can figure this out before next season because this was an issue this year and some of last year too...
I think alot of it has to do with the running game as well. If the offense can eat up some clock, the defense can stay off the field and rest up. The Giants' offense, when they scored, were usually pretty quick. So even when the defense did get off the field, without just a 3 and out, the offense would score so quick that they were right back on the field.
....and i thought this place was nutty during the season.
