I think it was AtlantaDan who posted somewhere about the cap space for 2020 and beyond. At first glance it doesn't look good at all! Something like $5 million or less. I'm just assuming the internet has the right numbers and did no comparisons across sites.
But, looking at this table, I think there are some pretty easy cuts that free up a decent amount of money:

Barron and Chickillo free up almost $10 million in cap dollars.
Moncrief is another $4 million.
Not sure I understand it, but using this tool:

I simply cut the three guys mentioned above and "Presto"! $16 million dollars in cap space.
I realize it is far too early to worry about any of this, but interesting side note.
