I have been saying for months that there will likely be a deal negotiated where they Owners and Union will agree to borrow from future cap in order to get the 2021 close to last years. This news gives them the ability to do that. (55% of the national media contracts goes towards the cap).
I read an article that basically stated this idea. They wanted to get the deal done soon so they could borrow from the future to help with the cap this year. I don't recall where the article came from though.
