Think of all the changes since 2011.

To try and get back on topic of the thread, there have been a lot of changes in personnel.

Since 2011, the Bengals have their fourth OC and third DC. Nearly all of the position coaches are different too.
It's pretty crazy to think AJ Green will turn 30 years old this year. It feels like he's only been around for 4-5 years, but it's been seven already. The Bengals will have to start thinking about finding that next superstar WR within the next 2-3 years probably because even if AJ can still play at a high level by that point, they need to start planning for that drop off like Atlanta did with Roddy White and Julio Jones.

I think 2020 will be that big year for a changing of the guard at key positions like WR and DL. Maybe LB too given Burfict will be turning 30 in late September 2020. Perhaps safety as well given Iloka also will be 30 and Williams will be 29 by the start of the 2020 season.
