We're certainly not witnessing a rising groundswell but for whatever reason his name was on the WSJ White House reporter Ken Thomas' list of potential Vice-Presidential candidates. Via the New York Post:
Kamala Harris’ campaign vetting VP candidates – but one major name not on list
Harris' campaign has requested vetting materials from potential VPs, including Cooper (NC), Kelly (AZ), Shapiro (PA), Whitmer (MI), Walz (MN) + Pritzker (IL), according to a person familiar. Beshear told CNN he hasn't been asked to submit info at this point.

And ominously for Vice President Harris Kelly is rumored to be the Chicago crowd's preferred candidate for President. For what it's worth, former Obama Attorney General Eric Holder is in charge of vetting the potential Veep candidates while his former boss has not endorsed Harris and instead has called for an open convention.
Additionally, here's the Arizona Repuplic headline from July 8:
Biden said ‘challenge me.’ At the DNC, Arizona Sen. Mark Kelly should
If all these, admittedly ephemeral, points do indeed mean the Senator is being maneuvered into position, here's hoping for V.P. Harris' continued good health. The Chicago crowd can play rough.
