Is it just me, or is there an unprecedented amount of uncertainty in the NFL right now?

This upcoming season the Saints, Panthers, Giants, Texans and possibly GB & Tampa may have huge rebuilds on their hands. Is it just me or is this one of the craziest times in the NFL with 9 head coach positions open, a young franchise QB (our own Buttboy4) looking to move, and 3 GM positions (1 filled), and 2 HoF QBs (Brady & Rodgers) potentially retiring.

I can’t remember a time in the past two decades where there has been this much uncertainty in the league?
