I have started supporting Juve before Del Piero was signed. Ever since the late 80s I've been following the black and white religion.
Baggio was a great player, an outstanding sportsman and a terrific Juve legend BUT, he did not give to the club as much as Del Piero. Whether it was number of goals, performances, games, trophies, sales..etc Del Piero wins in such comparision without any question.. That is a statement from a person who warships Roberto Baggio.
I agree with Rab, you really can't hate a Juve legend or some who who's given alot to Juve and be called a Juve supporter. You might be a Juve follower or admirer but not a supporter.
Lets take a player like Birindelli for an instance. This past couple of years he's been putting some terrible performances and seriousluy someone should be kind enough and ask him to retire. Although I get upset at him when he doesn't play well, I can never hate him. He was there for the during the good and bad days. he's carried trophies when we won and shared tears with us when we did not.
Another example is Alissio Tacchinardi, although he is not a Juve player now you cannot impossible hate him. During his time he was Juve's vice captain. He had been kickin for the biancioneri shirts since 1994. A year after Del Piero's arrival. Destroyed by Capello, he'll be always remembered in our hearts and minds as a true Juventino.
