The game just needs some new players and cards. I do not want to see it go back to the 60's. Then it just duplicates ATG. How about reshuffling the five seasons on many of the existing players, adding some new cards in the process. Then add some more players. There must be at least 100 players that would fit. If anything, the decade rule could be relaxed by adding players who began their careers in 87-88 but played into the 90's. (There aren't many 90's teams in ATG.)
At least shuffle the cards of the players currently available in the game. Otherwise, leave it as is. It's a lot of fun, especially if you also play ATG and 1969.
