sputtering staff, should I be concerned? WHIR

[gws226]

I've had this trully dominating staff in my 10 team h2h the first 2 1/2 months of the season, but they've been downright horrible the last month or so. Im usually patient with these matters... but maybe its time to be concerned and consider making a few transactions to either bulster my average offensive to compensate, or something else.

Adive appreciated

My SP staff:

Pedro---> Still dominate, but now being babied by Willie
RJ ------> 6.35 1.59 over the last month
Bedard--> fresh off injury
AJ ---> 4.46 1.33 whip over the last month
Colon--> 5.58 1.67 over last month
Webb--> 5.95 1.55 over last month
Haren--> 4.41 1.29 over last month
