Comparing # of SPO sites to Teams sites

Hi Ted,

All Microsoft Teams will have an SPO site, they don't work without them. (Funny story, had a user create a team, then go delete the SharePoint site "because he wasn't going to use that".  It broke everything.)

From what I understand, the "get-team" cmdlet only runs against a particular user to get the list of teams a user is a member of, and unless you specify an account it will just run against yours.  So, your suspicion is mostly correct in that you won't see those teams that your account has no access to.  Even if your account is a Global Admin (or even SharePoint Admin), https://docs.microsoft.com/en-us/sharepoint/sharepoint-admin-role.

If you haven't checked out the new SharePoint Admin center, you might browse through that to help identify all your sites and whether they are group-connected or not.  The new admin center give you a nice filterable list of everything that you can export if you want.
