Glouchkov knew very little English and was accompanied by Bozhidar Takev, a Bulgarian coach and trainer who translated for him. At the beginning of the season, Glouchkov impressed the Suns with his strong rebounding and became a regular member of the team's playing rotation; as the year went on, however, Glouchkov began gaining weight, and his productivity decreased. Some Suns' staff members attributed his weight gain to his taste for American fast food and candy, but rumors also surfaced that he was experimenting with steroids. He ended the 1985-86 NBA season with averages of 4.9 points and 3.3 rebounds per game.
