Forgotten past

Since it appears that the new manager's philosophy is to forget the youth movement for a year, why not sign Richard Hidalgo for 5 mil for 1 year.  Though probably not an upgrade in right, we might get lucky and Hidalgo might have a great 06 and then we can dump him for some minor league players.  Same with Casey after a year.  The "new philosophy" appears to be - try to get lucky for a year.  Though it has been so long ago, I believe in the golden years, when the bucs won consistently, you had mostly a complete team of homegrown talent and then management would bring in a special player from the outside like a Madlock to put them over the top.  Why can't we learn from history?
