The 2016 Cleveland Browns finished 1-15, ranking 28th in passing offense, 27th in receiving offense, and 31st in total yards allowed. Are the 2017 Jets worse?
According to ESPN's Football Power Index, the answer is yes.
"FPI believes the Jets are 7.9 points worse per game than the average NFL team, whereas the Browns were minus-7.4 last preseason, and it thinks all three parts of the Jets are a liability. The gruesome details: 5.2 points worse than average on offense, 2.1 points worse on defense and 0.6 points worse on special teams."
