Coaches comments during workout and the investigation...
Guys, here is the thing. It doesn't really matter, in the scheme of what happened, if the coaches made references to finding out who really wants to be a part of the program or not. The only way that would come into play would be if they overworked them and they did so to seek retribution for someone not being in the kind of shape they should have been in during the season.
It appears that others have had the SAME workout and not had problems. So, even if the coaches did want to make someone pay for not being in shape, it doesn't seem that the extent of the workout is what caused this, provided that fact is born out in the investigation as I have outlined above.
Something caused this to happen, and if it wasn't overexertion/lack of hydration/etc. then comments made by coaches during the workout, while not painting them in the best of light, will really be immaterial to the outcome and conclusion of the investigation.
