N.Y. Daily News: Team Roger Clemens rips into Wharton stats study

Wharton: Keeping up with the Hendricks?

The Hendricks brothers responded with their own analysis.

“The Clemens Report does not state that the statistics ‘prove’ anything, something missed by the four professors. The purpose of the report is to provide the statistical background of Roger Clemens’ career and to correct misconceptions about his career in the public forum,” Hendricks Sports Management said in a statement. “There are many variables at work that affect a starting pitcher’s longevity. For example, Roger Clemens’ workout regimen, which has been often cited as a significant factor in his success, has certainly extended his career. Just because it is difficult to measure the impact of a challenging workout regimen does not mean it does not favorably impact performance. Another factor that helped Clemens remain effective was his ability to adjust his pitching style over time, something the professors choose to disregard because pitch selection is not quantified in the report.”

...“As Bill James stated in a salary arbitration case while working with Hendricks Sports Management, ‘Anyone can make a chart.’ The professors have proven this axiom, but they have not added anything substantive to a discussion of Roger Clemens’ career,” Clemens’ agents said.
