How do extensions work?

Also worth noting on extending contracts, first round draft picks are unique in that teams can exercise a 5th year option and keep their first round draft picks an extra year. Teams need to do this before the start of the players 4th year. Last year the Bengals picked up the 5th year option on Jonah Williams. This year would be Burrow's 4th, next year will be Chase's. The Bengals can and almost certainly will pick up the 5th year option on both Burrow this year and Chase next year.

Tee being a second round pick doesnt quality for the 5th year option so this next season will be his last unless he signs a new contract.
