The series really exploded on the PS2, but it's still playable (and pretty good) after all these years
On the downside, the franchise mode is pretty weak when compared to what you'd be able to do with it just a couple years later. You can draft, sign and trade players, but that's about the extent of it. If you're expecting to be able to change ticket prices, renovate your stadium, create promotion days and things of that nature, you should definitely look elsewhere.
If you're looking to relive the old days with this game and are worried that it might be unplayable anymore, put your worries to rest and get the game.
