The offense lost several games last year in the 2nd half, by not converting key 3rd downs or not closing out games.
Today was similar. The 2nd half was almost all 3-and-outs for the offense, and left the defense out there to fry.
Someone in another thread showed that last year 2/3 of the Patriots' points were scored in the 1st half and only 1/3 in the 2nd half, a far departure from the 50/50 split over the past 10 years. This season, small sample size but it's up to 75%/25%.
Any skilled defensive coordinator is going to continue to eat us alive until O'Brien learns that play calling is a lot more like playing poker than it is about relying on just execution. This team has a very real issue with getting outplayed in the 2nd half of games.
The talent excuse doesn't cut it anymore. One can't throw the tight ends and 3rd receiver under the bus, like they were used last year as scapegoats. This year's offense has 3 legit tight ends, plus more talented receivers after Moss and Welker. The issue isn't talent, but play calling which has an influence on ability to execute.
