What Are Bill Belichick's Other Horcruxes?

Seeing as how Lord Belichick inadvertently revealed the nature of one of his Horcruxes today, we thought now would be a good time to try and figure out what items house the other six pieces of his sundered soul. These are our guesses, and please feel free to share your own in the comments.

The one ball from the AFC Championship game that wasn't deflated ( h/t @Dr_Magnifico)

The original copy of the Spygate video

His first hoodie

The Helmet Catch ball

His old Browns playbook

Adam Vinatieri

I'm confident that at least two of those guesses are correct. Please share your ideas the comments.
