Possible ABA Memphis Pros Basketball Jersey?

[both-teams-played-hard]

A fellow collector asked my opinion about this jersey. Same colors as the ABA's Memphis Pros from the early 70s. We have both never seen photos of the Pros wearing this style jersey. The Pros last season was 1971-72. Could this be a prototype of a un-used style? The Wilson tags seem to be from the mid-70s. Could they have been used in late 1972?
Any thoughts and opinions are appreciated.
