Made the connection today.
Didn’t get off the plane until about 6:57 in the B terminal and the flight to BOS was departing C61.
Hustled through the FCC and made it to the gate as group 3 was being called... Of course, I also got SSSS’ed so I was ended up taking my seat after almost everyone boarded.
As an aside, 3/4 checked bags in our group made it. The one that did not was an oversized piece.
