Well, on closer looking, it's not.
These GMs have been online during the last 12 hours:
Celtics, Pacers, Nuggets, Kings, Suns, Spurs, Wizards, Cavs, Knicks, Heat, Warriors, Clippers, Magic, Nets, Pistons, Sonics ... and Raptors (despite the massive handover from turning 21 yesterday)
These GMs have been online during the last 24 hours:
The 17 GMs above plus Bucks, Jazz, Hornets, Mavs, Rockets and Sixers.
The Blazers have been on 2 days ago.
Making that 17 hyper-active GMs, 6 active GMs, one semi-active GMs and one missing Commissioner and simmer.
The rest of the teams (Grizzlies, Lakers, Bulls and Wolves) apparently run on cpu control as of now, might be the time to do some recruiting since the new season is about to kick off ...
