text: If your staff is strong, keep him through June.  If your staff is killing you now, keep him through June.  You are concerned about your history with young pitchers.  Now you are talking about getting Jered Weaver instead. Zack Duke is young and has won before.  If you are concerned about bad numbers in a roto league, bench him.  If you are in a head-to-head league, play him anyways.  One bad start might hurt your ERA, but you will want the other stats like Wins and Strikeouts.  I would much rather have a young pitcher in a slump than an old pitcher doing poorly (Radke).  The old guy will only get older, the young guy can get better.
