After the war, Blandin signed with the Cleveland Browns in 1946 as the team geared up to play its first season in the All-America Football Conference. He rotated at left tackle with Chet Adams in 1946 and 1947. The Browns won the AAFC championship both of those years. By early 1948, the league was looking for ways to distribute talent more evenly across its teams, and several Browns players, including Blandin, were sent to the Baltimore Colts to help the struggling team.Paul Brown, Cleveland's coach, called Blandin "one of my best men" and insisted that the AAFC's commissioner, Admiral Jonas H. Ingram, tell Blandin that the move was Ingram's decision.
Blandin played at left tackle for the Colts until 1950, when the team ceased to exist. He left football before returning for one additional season in 1953 with a newly re-formed Colts team.
