I think its because
(1) Matt Patricia
(2) Complete lack of weapons
(3) History of providing subpar weapons to QB
Could we stop with the BS of "Complete lack of weapons". It's false and it's a complete insult to the players here.
RB - Harris, Michel, Taylor, Bolden
WR - Edelman, Meyers, Harry, Olszewski
TE - Asiasi, Keene, Izzo
Harris, Michel, and Taylor give the Patriots a Top 5 RB group. San Fran, Dallas, Houston, Arizona are the only ones better, IMHO. Harris, Michel and Taylor teased us with what they can do in the receiving game. Bolden did decently in the receiving game in 2019, but it remains to be seen if the Patriots keep him or decide to move on.
Yes, Edelman is old. Who knows if he'll be back. But for now, he's the Grizzled veteran of the group. Olszewski looks like he's rounding nicely into a similar type of player. Meyers looks to be the next Givens. With even a DECENT QB, Meyers should put up 1000 yards on a season.
Harry is still an enigma. He's not as bad as the haters on here have said. He has room to grow for certain.
I wouldn't be surprised if the Pats brought in another WR either in the draft or through Free Agency just to keep things fresh. We may also see Byrd back. A decent QB would probably life him up close to 800 or 900 yards.
Asiasi and Keene are unknowns because of the COVID season and the injuries both suffered that hampered the season further. But NO ONE knows what we have in them. Both teased us. Izzo is under-rated by many. He finished the season catching 10 of 12. But, with the team being a Run first team and the issues at QB, the reality is that our passing game in ALL aspects was hampered.
This BS that the Patriots has a history of providing subpar weapons is also complete BS. People seem to forget that they went out and got the likes of MOSS, WELKER, and AMENDOLA. That they traded for Cooks.
Anyone who looks at the 2020 season and thinks that it's representative of the Pats offense needs their head examined. Newton's inability to throw passes hurt this offense tremendously. I said it before and I'll say it again, the reason that Newton's completion % was at 65.8% was because of the RECEIVERS and not Newton. They're the ones who caught his ill-thrown passes on a regular basis. I think I can count on both hands the number of well thrown passes by Newton on the entire season. Newtons inability to read defenses properly and to throw the ball on time really hurt this offense.
