Brady, Edelman work out in California

On the day before free agency begins, quarterback Tom Brady and receiver Julian Edelman worked out together in California, a reflection of the connection they've developed over the last five years.

Edelman, of course, is a free agent who is free to sign with any team as of 4 p.m. ET on Tuesday.

The Patriots and Edelman's camp have expressed mutual interest in a contract extension, and they continue to communicate about a possible deal.

In the end, however, the market will ultimately dictate, as the Patriots' proposals haven't been enticing enough at this time for Edelman to commit to it.

Similar to last year with Wes Welker, if a deal isn't struck by the start of free agency, it could lead the Patriots to their next option. That potentially makes the next 12-18 hours a critical time for both sides.
