In 2008 the set Jumped the Shark.
For the first time, the set included active players. Sorry, but Carlos Zambrano is not legendary. Psycho, yes; legendary, no. And even worse, the active players made up the 100 card base set while the actual legendary players were short-printed. Jumping the shark even more, Upper Deck went all Allen and Gintery by making the first 46 short prints non-baseball players. You want a Claude Monet or Richard Nixon--then we've got the set for you.
The sad part is I really like the design of the cards. Too bad I end up with Alfonso Soriano along side Billy Williams.
Four Cubs were included in the active player base set:
Four more Legendary Cuts regulars were in the SPs, actual Legendary players
