You're completely ignoring a couple small facts.
We are down an all pro tight end in hernandez and who knows if gronk is ever at full strength this season. Amendola didn't even make it into the regular season before getting hurt and then he got ANOTHER injury. And to top it off vereen is out for at least FOUR weeks and Ridley got benched.
1) They won a divisional game on the road.
2) They ran more offensive plays than any team other than possibly the eagles, who were on a record setting pace at the half last night.
3) Their defense held the Bills to two scores and shut down one of the better running backs in football in CJ Spiller.
4) They still have the GOAT QB, and he has NEVER had a bad season, regardless of the weapons he had around him.
5) Ridley is available this week, and one of the better RB's in the league when he is out there.
6) Gronkowski is on schedule to return earlier than anyone ever expected.
7) Amendola is nicked up, not dead, and when he was out there looked like outstanding, and like a really good prospect to replace much of Welker's role and production.
8) Edelman played really well and looks like he can contribute significantly this season, which would be a first as a receiver for them.
The Patriots have questions and challenges ahead of them, but they also have an unparalleled track record of meeting those challenges and questions. i don't expect them to dominate at any time this season but still have a great deal of faith that they will be really competitive and will be in the hunt come january. they may not have what it takes to win it all this season but they are still a good football team and their future is bright even if they still have some needs to fill down the road.
