i agree with Brian C. "No
At least in all my experiences.
Certain guys just dont seem to perform.
while others overperform"

if possible hook up with another owner in your league and exchange some underperformers from each team. Change might do them good.

What a week, I have five teams turns out all of my teams are on the road this week won 19 of 20 one series yet to be played. ya I had a few overperformers:)

Ps have to factor in staduim effects and type of pitching/hitting in your division too.
