Julian Edelman announced his retirement from the NFL two weeks ago, and it didn’t take long for rumors to develop about a Tom Brady reunion.

Though Edelman retired due to his balky knee, some wondered whether he might one day come out of retirement to rejoin Brady on the Tampa Bay Buccaneers, just like Rob Gronkowski did.

Brady seems to be in on the rumor.

Edelman posted on Instagram about the jersey number debate and suggested Brady wear pi as his jersey number. Brady responded by saying, “Now that you are a free agent, are you buttering me up??”
