Both you and the parent comment are correct.

Some states (Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut) ratified the Constitution before the Bill of Rights was formally drafted[1] and initially without requiring the Bill of Rights. The Massachusetts Compromise was an agreement that the Bill of Rights would be packaged with the new Constitution (with the BoR being active at ratification, before the Constitution) and was required before some of the remaining states would ratify the Constitution.

It's worth pointing out that the Bill of Rights was ratified 2.0 years after the first elections for national office and 1.5 years after the constitution was finally ratified. [1]
