As someone who targeted Eric Chavez at this year's draft and let him go for $31 only to see him have a great start to the season (.301 AVG 9 HR 20 RBI), I admit to some schadenfreude seeing him struggle so much since.
(I also admit to having suffered Chavez's abyssmal start to the 2005 season - at $41!)
With an equally abyssmal 3 months since that wonderful, MVP-inspiring (finally!), flower-inducing shower-filled month, he has stunk.
With that type of performance, he has cemented himself as a "worthless" fantasy player.
With 3/4 of the season over, Chavez's full-season numbers will never look good. However, I point out that he is 7 for his last 18 with a HR and 2 doubles.
Could this be a lucky 18 AB stretch? Sure. Could it mean he is over/adjusted to his physical issues? Yes.
On that possibility, I suggest acquiring him for the final 40 games. He will not cost anything and likely could be had for a non-active piece on your roster.
You could get lucky.
