I think he's played well for us for the most part and should be retained. How much interest is a injury prone, rotational DE gonna command on the open market? He's making 12.5 right now and will probably see the same next year if he stays.
I know Josh hasn't played well lately, but it's really hard to constantly bail your team out when who have receivers stopping on routes, dropping passes and your RB fumbling all on his own.
Add injuries and Brady's playcalling and it's a tough ask.
