I believe the jets front office was a joke
i also believe changing systems sometimes takes time
(Jets situation is different with fitz he knew the offense and he is the key part running it)
The defense can usually be improved in year 1 but I believe this was Rex's issues he didn't have the parts to run his defense and was stubborn to change would most likely cost us the playoffs
If nothing changed last year would u expect this team to be anywhere else record wise (7-9 /8-8)
