In response to rtuinila's comment:
Correct me if I'm wrong but, aside from Blount, isn't all of last years O returning? Besides bolstering the O-line I don't think the Pats "need" anyone. They had the third ranked O last year, so they already have enough talent. How much better do you think they can get?
But then again, I am not a fan of fantasy football!
Here's some interesting stats:
Points per game
Final '13 ranking: 3rd (27.75)
Last season: 1st (34.8)
A full TD lower than previous year
Final '13 ranking: 16th (83 of 221, 37.6 percent)
Last season: 1st (110 of 226, 48.7 percent)
A drop of over 10% from the previous year
Red zone offense (based on TD percentage)
Final '13 ranking: 15th (36 of 65)
Last season: 1st (49 of 70)
a full 15% drop
Most of those numbers come from a handful of games which Gronk was playing. In games Gronk played they averaged 32 points per game and both 3rd down efficiency and RZ efficiency went from bottom 1/3rd of the league to top 5 in the league. When Gronk wasn't playing they averaged 21 points per game (which puts them in the bottom 1/3rd of the league and the 3rd down and RZ efficiency dropped like a rock. With Gronk this was a top of the league O, without Gronk this team was a bottom 1/3rd of the league O. Stay for the blowouts at the end of the year against the Ravens and the nothing to win for Bills the numbers would shift even further. This was not a #3 O in the league last year. At it's best it was but for half the season it was a below average O.
