Ervin Santana ... Ugh

I snagged a 2004 Bowman’s Best autographed rookie card of Ervin Santana on Listia.  The cost was 1,121 credits.  That’s not too bad for a certified autograph and a rookie card all in one.  I made this purchase despite the multiple occasions on which Santana disappointed my fantasy team this season.  He was so bad that I eventually cut him.  He was downright horrible.  Santana is now a Royal, so that should work out well.  Why did I buy this card again?
