Lots of creative revisionist history and targeted propaganda going on. Comparing teams from the early 2000's to now is silly. The game today is so different. For example, there were 11 QB's with 4,000 passing yards this season and 12 last season. In 2001, there were 2.
Top skill position players on NE's SB teams:
2001: Smith, Faulk, Brown, Patten
2003: Smith, Faulk, Patten, Brown, Branch, Givens, Graham
2004: Dillon, Faulk, Givens, Pattem, Branch, Graham
2007: Maroney, Faulk, Morris, Moss, Welker, Stallworth, Gaffney, Watson
2011: BJGE, Woodhead, Ridley, Welker, Branch, Gronk, Hernandez
2014: Vereen, Ridley, Blount, Edelman, LaFell, Amendola, Gronk
2016: Blount, Lewis, White, Edelman, Hogan, Amendola, Mitchell, Gronk, Bennett
2017: Lewis, White, Burkhead, Cooks, Amendola, Hogan, Gronk, Allen
2018: Michel, White, Burkhead, Edelman, Gordon, Hogan, Patterson, Gronk, Allen
After the year they rolled out the corpse of Troy Brown and Reche Caldwell, they added Moss, Welker, Stallworth, and Gaffney. That 2006 (237 points allowed) was very similar to the 2019 team (225 points allowed).
Anyone suggested that NE will roster the same offense next year is choosing to ignore that NE will try to address their flaws. Clearly the last two seasons the offense has not had the same talent level and play makers as years past. People also need to remember that there are teams now that can score in buckets when 15-20 years ago those teams were hard to come by.
The Pats have tried to address some of their issues on offense the past few seasons. The problem is they didn't work out.They will go back to the drawing board for next year and make changes. Maybe those will work out, maybe they won't. But they are not going to just stand pat and the roster the way it is. Having guys new to the system and having multiple players get hurt were a big part of what derailed the offense. That won't help any team's chances.
And it's also silly to play the what if game for who NE DIDN'T draft over the years. Plenty of draft picks don't work out for all teams and every other team in the league has passed on plenty of players that turned out to be stars. There is a ton of luck involved in landing players that turn out to be productive.
I also will reiterate that 3/4 of the league would kill to have a 12-4 team and make the playoffs. Had many of those teams accomplished that, those teams would be looked at as top contenders next year. Yet for NE, it's woe be gone, the end is near, and they are staring at a 5 win season next year. And again, until we know how the roster and coaching staff looks for next year, it's a fool's errand to try to make any sort of educated prediction or analysis for the 2020 season.
