Zeke to the Bengals?

Pass on any aging running back.

I've seen too many elite running backs hit a wall and never recover.
Are there any exceptions (Adrian Peterson kind of)?

With the way we are structuring this team (putting big money into the QB and 2 WRs),
I am of the opinion that we need to rely on drafting running backs (every 3-4 years) and getting bargain tight ends (and drafting them as well).
