I've been loving these posts, Al. It's been funny to see that we've flip-flopped on what we think of some sets, but that's part of the fun of this! You didn't care for 1976, and that's my favorite. You've liked 1978 and that's one of my least favorites from that time. I liked the colorfulness of some of the previous sets, so 1978 seemed a little drab.
I do remember "Gor" coming up and having high hopes. I don't remember the specifics on his leaving the Twins and coming back, but it did seem to ring a bell. That he played 89 games for Tacoma in 1975 and only 39 for Denver makes one think that the transaction happened after the June 15 trade deadline that I think was still in effect at the time. That, and hitting just .239, sorta points to being waived, but that's speculation. He tore it up for Denver, however, so if the Sox then declined to keep him, one could see the Twins wanting to take a second chance.
The Google machine did have a couple links that seemed to offer potential on his story, but they were behind paywalls. Another snippet said he was the 200th player to appear as a Twin.
While Googling, I did find this: https://wpial.org/hof.aspx?hof=19. It says he had committed to Penn State football after having received offers from Ohio State, along with Pitt, Maryland, Miami, Michigan, North Carolina State, and Notre Dame. He'd rushed for 3,350 yards in his career.
