I wouldnt say that.
Winkler, Carle, Freeman, Viz, Minter isnt terrible, and Biddle has looked ok lately. Moylan is decent as a middle relief option. Our 7th-8th guy are pretty bad but when you're complaining over your 7th-8th BP pitcher, you're complaining just to complain.
Also Viz has pitched like 4 times since May 16th or so, he's hardly been over-worked.
