Chief showed signs of vulnerability as far back as 2005 (second half of the season). I've given up on Chief.
He really is all over the place - which stinks because I've always really, really liked him - when he was 12 of 13 saves last year I had high hopes that he was getting back to "2005 form" ... but he's struggled with his location so much this year - doesn't even look like the same pitcher ...
