Eddie Shore liked what he saw when he first scouted Atanas and assigned the right winger to his AHL team in Buffalo. While there, "Ants" displayed his trademark blistering shot and blazing speed and was a significant part of the Bisons league championship that season.
The next year, Atanas played with the Rangers while their war-torn roster was in the Army, and he had a perfectly acceptable season, scoring 13 goals. But the Rangers missed the playoffs and pre-war players were starting to return from action to reclaim their sports with the team. Atanas was buried in the minors for more than a decade, never to see the NHL again.
He played for the famous Minneapolis Millers in the USHL, and joined a variety of teams before settling in with Shore's newest purchase, the Springfield Indians. After four years, he played a final season in North Bay and then retired in 1957.
