Especially considering there are other unrelated branches between them, of varied origins(Mostly Western). I-Y3120 is only dated to 100BC and it accounts for the entirety of I2a1b-Din that he refers too, downstream of CTS10228(basal samples which appear around Germany/France).
He also forgets, even if for the sake of argument, that I2a1 was in mesolithic Balkans, the cultures they are trying to affiliate it with didn't exist until the bronze age. Including their language, and to some degree their genetics. Unless they find a branch downstream of CTS10228, and upstream I-Y3120 in the Bronze/Iron Age Balkans, its only support outside of a Slavic origin is Germanic. This however does not change that most I-Y3120 branches moved almost entirely in the middle ages with Slavs. Excluding the Greek branch which is somewhat a mystery.
