Rams are projected salary cap by Sportac website, after Ogletree signing to have 43.9 million under the cap. This includes a five million dollar rollover from last year the Rams chose not to employee.
The following players would have the following cap savings if cut (although each would create "dead money", the savings is the amount over dead money saved):
Quinn-11.4 million
Barron-7.0 million
Saffold-6.5 million
Whitworth-6.3 million
Brockers-4.2 million
Austin-3.0 million
Gurley-2.3 million.
Quinn will have to take a cut and Barron and Saffold would be easy restructures. We would have nearly 60 million dollars.
I believe Donald, Joyner and Watkins could easily fit.
Additionally the Rams would be getting potentially two third or fourth round compensatory picks in 2019 if Watkins and TruJo are deemed expendable in free agency.
