Btw, a quick look at mostly Eastern- and Central-Iranian languages
gave the following results:


Pers. pron. 1st. pers. sg.:

Yazgulam: az
Ishkashim: az
Shugn-Roshau: as/az
Avestan: azUm
Pashto: zU
Ossete: az

Having in mind the archaeological evidence analyzed by D.Dimitrov and
the supposedly close ties between Protobulgarians and Ossetians, and
the supposed previous coexistence with Central and Eastern Asiatic
peoples, it is definitely simpler to think up an explanation through
the fictitious Protoslavic (where you can think up everything,
following logical patterns) than to just point out what I would call
direct evidence. It is, indeed, simpler to get from here to London
through the North pole.
