Didn't Ty Cobb used to be in the game? Idk why they removed him.
Even when he was active, it was hard to get Barry Bonds to be in videogames, so he's probably a tricky one to get the rights for. And Pete Rose obviously has a very controversial history.
That being said, Troy Tulowitzki being the best card in the game is kind of laughable. I'm a bit surprised they couldn't find somebody better than him to be the best card. I'm happy he's back in the game, but he's probably the worst headliner-type player I can remember them releasing and promoting this much.
