I'd like to understand the workings of the salary cap a little better - in particular, carrying over cap space from one year to the next. I wonder if anyone here can help answer my questions.
Basically, as I understand it, teams can carry over any amounts by which they come in under the cap into the next year, and this can carry on from year to year. Am I right about this?
I've found 2 places which seem to show how much cap space is left for each team, and their numbers broadly agree: http://overthecap.com/nfl-cap-space.php?Year=2013 and http://www.spotrac.com/cap-tracker/nfl/.
So, my main question is - are the 'cap space' figures in those 2 links a guide to the extra amount the Eagles should have available for future years? The Eagles seem to have $17,000,000 which is 4th in the NFL and 1st in the NFC; next highest in the NFC is Carolina with $12,300,000, so a fairly big gap. The average team seems to have about $3,000,000 cap space.
If this is right, I also wonder about how important it is. It might allow $5,000,000 extra spending a year over 3 years, say. Since the total cap is about $120,000,000, this seems a modest but not insignificant amount.
Thanks for any help!
