Could the Slavs have brought down the Roman Empire?

I realize that Germanic, Iranian, and Altaic-language speaking people
(the Huns) brought down the Roman Empire in 476 AD.  Well,
geographically between the Germans and the Iranians are the Slavs.
Could it be possible that they too also contributed to the fall of the
Roman Empire?

I personally think that the term "Germania" in those days also
included Slavs and Baltics.
