 At 211 cm tall, and with a peak weight of 120 kg , Sandilands became the heaviest and equal-tallest player to ever play in the AFL.

 At the beginning of the season, the word "Athletics" returned, in script lettering, to the front of the team's jerseys.
 Former A's owner, Charles O. Finley banned the word "Athletics" from the club's name in the past because he felt that name was too closely associated with former Philadelphia Athletics owner Connie Mack.
 In his first full Major League season, Mark McGwire hit 49 home runs, a single-season record for a rookie; he was named the American League Rookie of the Year.
 McGwire would be the first American League rookie since Al Rosen of the Cleveland Indians in 1950 to lead the American League in home runs.
 The 1987 season also saw the return of Reggie Jackson to Oakland.
