Salary Cap Conversation

Wanted to spark some discussion based on what I'm hearing about salary cap concerns in the future. I created a simple Excel doc where I line item starting positions and assign these starting positions a % of total cap space. Essentially, prioritizing what positions get how many of the limited dollars. I have attached a rough draft of my first attempt as a pic. Also, this is generous--it does not consider all the backups, special teams players, dead money, rookies, etc. So, the dollars are much less(maybe 10-15%) in reality.

Would love to hear people's thoughts. Happy to massage the numbers if anyone is interested.
