Patriots have the 11th most salary cap space.  This despite all personnel they brought in and the new Gronk contract.  The article is current so the numbers are probably accurate as of July 1st.

What's even more surprising is that the Pats have the most available space in the AFC East.  I expect the Jets to be close to the bottom with a bunch of clowns running their circus show.  But a team like Miami?  Who exactly have they signed?  Weren't they having a hard time signing FAs?
