I have a suggestion for CapFriendly:

It would be interesting to be able to see the Dead Cap used by all teams by year in a single page.

This is for comparison of team management of cap space (i.e., which team has a good/bad records with managing their cap; which teams have hand-cuffed themselves with bad deals).

If this has been suggested already, my apologies - I didn't see it in my forum search.
