No, I'm saying that there's absolutely no way to determine that it was without a HUGE body of evidence. Common sense suggests it's highly unlikely though. I'm concerned with the part relating to the arm, because that is what the program is targeting - and the part with the biggest implications for a pitcher.
I'm not looking to do that at all, but rather trying to reasonably narrow the focus. Cecil and Delabar are legit questions that need to be explored further to see if there is causality. Janssen had the lowered velocity prior to starting the program, and said several times during the season that he could feel the difference with how his arm felt after using the program for a while. He was excited to see the results of what a full offseason on it would produce.
My original response was just wondering what point you were trying to make, since the subjects were disconnected and no explanation was given for the presentation. Regardless, this is way off the original point which was that the club must be very confident in the program to roll it out organization wide with very little available information about the effects. Whether one or two of those guys are or aren't included doesn't change that.
