My Most Recent Kellogg's Set Purchase - What Happened to Player Selection?

Recently I purchased a 1977 Kellogg's baseball card set.  The set seems odd because there is no Nolan Ryan, Reggie Jackson, Mike Schmidt, Gary Carter, Lou Brock, Willie Stargell, Johnny Bench, Carlton Fisk, Fred Lynn, Jim Rice, Joe Morgan, Rich Gossage, Jim Hunter, Phil Niekro, Don Sutton, Bert Blyleven, Robin Yount, Carl Yastrzemski, Willie McCovey, Gaylord Perry, Bruce Sutter, Tom Seaver and Jim Palmer among others.

What happened to player selection for this set?  I realize that not all of the players listed above had good years in 1976, but to leave all of them out didn't work so well.

The 1977 set seems to be forgotten because there are no real high-powered star cards.  By a quick count, there might be about six Hall of Famers in the set.  That's far less than any of the other main sets.  I think that 16 players featured in the 1977 set never got into another Kellogg's set.

Usually Kellogg's throws star power into the first nine cards.  This group has only two Hall of Famers.

Did any other Kellogg's set have a similar lack of star power in its first nine cards?  I'll need to check that out.

 Soon I will check out the card backs.  Kellogg's took quite a risk with player selection so how did they do with the card backs?
