Just for reference and because people will wonder about this. The Rams estimated Cap Space for 2017 is ~$45 million.
The annual cost of running a team = ~$10 million. This is a sample from 2016. The Rams FAs for 2017. The will also have to decide if they want to exercise the 5th year option on first round picks Robinson and Donald. That doesn’t affect the Salary Cap until 2018. After the 5th year option, the Rams can still use the Franchise Tag [2019 for Donald]. Donald isn’t going anywhere for a long time.
