It actually feels like there are bad offenses everywhere in the nfl.
There's more than a couple longterm QB's whose offenses haven't gotten off the ground this year, some past their prime and some who knows. Guys like Eli are at the end of their rope and we're just now realizing it. Cam may never recover from that SB crushing. The Seahawks seem dead in their tracks now since OL and the gradual eroding of their thick stable of playmakers has taken hold. The latest crop of young QB's like Goff and Watson haven't solidified themselves as legitimate while Luck and Tannehill have been hurt. Dak is gonna have to deal with the struggles of a Sophomore who teams will just now be figuring out and will have to adjust. The Bengals have always been boom or bust but were all bust through two weeks and fired their OC.
There is offense happening, but its not coming from the places that people anticipated this year.
