Clay is due $15M ($4M is dead cap) for 2017.
He is due $11.4M (with no dead cap space) in 2018.

I believe the Packers will leave his contract alone and see what he produces in 2017 (health and stat wise). He will be 31 going into next season. A good season this next year, and the $11M hit in 2018 doesn't look unreasonable. If things don't pan out, they lose nothing if they decide to move on in 2018.
